Prime Factors of 7429
By prime factorization method, we can write the prime factors of 7429 as given below.
Step 1: The first step is to divide the number 7429 with the smallest prime number, i.e. 2.
7429 ÷ 2 = 3714.5
As we know, the factors cannot be a fraction, therefore, 2 is not the prime factor for 7429. So proceed to the next prime numbers, i.e. 3, 5, 7 and so on.
7429 ÷ 3 = 2476.33
7429 ÷ 5 = 1485.8
7429 ÷ 7 = 1061.2857
7429 ÷ 11 = 675.3636
7429 ÷ 13 = 571.4615
7429 ÷ 17 = 437; 17 is a prime factor of 7429.
Step 2: Now, we divide 437 by 2.
437 ÷ 2 = 218.5
As we know, the factors cannot be a fraction, therefore, 2 is not the prime factor for 437.
Step 3: Now, proceed to the next prime numbers, i.e. 3, 5, 7 and so on.
437 ÷ 3 = 145.66
437 ÷ 5 = 87.5
437 ÷ 7 = 62.4285
437 ÷ 11 = 39.7272
437 ÷ 13 = 33.6154
437 ÷ 17 = 25.7058
437 ÷ 19 = 23; 19 and 23 are prime numbers and hence, we cannot proceed with the division method.
Thus, the prime factorisation of 7429 can be expressed as 17 × 19 × 23.
Prime factorisation of 7429 is: 17 × 19 × 23 |
Prime factors of 7429 are: 17, 19, and 23 |
Note:
The exponents in the prime factorization of 7429 are 1, 1, and 1. By adding one to each and multiplying them we get, (1 + 1)(1 + 1)(1 + 1) = 2 × 2 × 2 = 8. Thus, 7429 has exactly 8 factors.
