 # Square Root of 3721

The square root of 3721 is 61. The square root of a number with its solution is represented as √3721 = ±61. When a number is multiplied by itself, the product is termed as the square number. To determine the square root of 3721, we need to identify the number x, such that x × x = 3721. Note that the value of x can be either positive or negative as it is being multiplied by itself. The product, however, will be positive only. The methods to determine the value of x are the prime factorization method, Repeated subtraction method and Long division method. All these 3 methods are detailed in the article below. You can find ways of Finding Square roots.

## How to Find the Square root of 3721?

There are three methods to find the Square root of 3721

• Prime Factorisation method
• Long Division method
• Repeated Subtraction method

### Square root of 3721 by Prime Factorisation Method

The Square root of 3721 will be obtained only if 3721 is a perfect square number. In this method, let’s divide the number with prime numbers. Since 3721 has only 1, 61 and 3721 as the prime factors. Dividing 3721 with 61, and grouping 61 and removing 61 from the root forms the square root of 3721.

The given number, 3721 will be expressed as;

 61 3721 61 61 × 1

3721 = 61 × 61

√3721 = √(61 × 61)

√3721 = 61

Therefore the square root of 3721 = 61.

### Square root of 3721 by Long Division Method

Follow the below mentioned steps that details the long division method;

Step 1:  Grouping the given number into pairs

The given number is 3721, grouping it as 37 and 21.

Step 2: Let us find a square number that divides 37

i.e.,

4 × 4 = 16

5 × 5 = 25

6 × 6 = 36

The square number that is to be considered for dividing 36 will be 6 × 6 = 36

Step 3: Continue the division using the next number 21 The division is complete as the remainder is zero. Hence the quotient is the square root of the given number which is 61.

Therefore the Square root of 3721 is 61.

### Square root of 3721 by Repeated Subtraction Method.

For finding the square root of 3721 using the repeated subtraction method, 3721 is first subtracted by 1, the resultant by 3, the next resultant by 5 and so on. The subtraction is stopped when the resultant becomes zero. The step at which the result becomes zero, forms the square root of 3721. Let us find the result in the table below. If the process of repeated subtraction leads to a negative number, then 3721 is not a perfect square number and thus will not have a perfect square root.

For the given number 3721, steps for repeated subtraction are

 Step 1 3721 – 1 = 3720 Step 2 3720 – 3 = 3717 Step 3 3717 – 5 = 3712 Step 4 3712 – 7 = 3705 Step 5 3705 – 9 = 3696 Step 6 3696 – 11 = 3685 Step 7 3685 – 13 = 3672 Step 8 3672 – 15 = 3657 Step 9 3657 – 17 = 3640 Step 10 3640 – 19 = 3621 Step 11 3621 – 21 = 3600 Step 12 3600 – 23 = 3577 Step 13 3577 – 25 = 3552 Step 14 3552 – 27 = 3525 Step 15 3525 – 29 = 3496 Step 16 3496 – 31 = 3465 Step 17 3465 – 33 = 3432 Step 18 3432 – 35 = 3397 Step 19 3397 – 37 = 3360 Step 20 3360 – 39 = 3321 Step 21 3321 – 41 = 3280 Step 22 3280 – 43 = 3237 Step 23 3237 – 45 = 3192 Step 24 3192 – 47 = 3145 Step 25 3145 – 49 = 3096 Step 26 3096 – 51 = 3045 Step 27 3045 – 53 = 2992 Step 28 2992 – 55 = 2937 Step 29 2937 – 57 = 2880 Step 30 2880 – 59 = 2821 Step 31 2821 – 61 = 2760 Step 32 2760 – 63 = 2697 Step 33 2697 – 65 = 2632 Step 34 2632 – 67 = 2565 Step 35 2565 – 69 = 2496 Step 36 2496 – 71 = 2425 Step 37 2425 – 73 = 2352 Step 38 2352 – 75 = 2277 Step 39 2277 – 77 = 2200 Step 40 2200 – 79 = 2121 Step 41 2121 – 81 = 2040 Step 42 2040 – 83 = 1957 Step 43 1957 – 85 = 1872 Step 44 1872 – 87 = 1785 Step 45 1785 – 89 = 1696 Step 46 1696 – 91 = 1605 Step 47 1605 – 93 = 1512 Step 48 1512 – 95 = 1417 Step 49 1417 – 97 = 1320 Step 50 1320 – 99 = 1221 Step 51 1221 – 101 = 1120 Step 52 1120 – 103 = 1017 Step 53 1017 – 105 = 912 Step 54 912 – 107 = 805 Step 55 805 – 109 = 696 Step 56 696 – 111 = 585 Step 57 585 – 113 = 472 Step 58 472 – 115 = 357 Step 59 357 – 117 = 240 Step 60 240 – 119 = 121 Step 61 121 – 121 = 0

Since the result of zero is obtained in the 61th Step, the square root of 3721 is 61.
