The HCF of 3 and 4 is 1. HCF of 3 and 4 is the greatest integer that can divide these numbers evenly, and that number is 1. HCF stands for Highest Common Factor, and it is also known as GCF, Greatest Common Factor or GCD, Greatest Common Divisor. For the given set of numbers 3 and 4, there are no common factors other than 1. Hence 1 is the HCF for 3 and 4. You can refer to GCF for more details.
What is the HCF of 3 and 4?
The Highest Common Factor, also known as the Greatest Common Factor, of 3 and 4 is 1.
How to Find HCF of 3 and 4?
There are three methods to find the HCF of 3 and 4:
- Prime Factorisation
- Long Division method
- Listing common factors
HCF of 3 and 4 by Prime Factorisation Method
In the Prime Factorisation method, the numbers can be expressed as the product of prime numbers. Here, 3 and 4 can be expressed as:
3 = 1 × 3
4 = 2 × 2
As there are no Common Prime Factors between 3 and 4, the HCF will be 1
HCF (3, 4) = 1.
HCF of 3 and 4 by Long Division Method
In the Long division method, the below steps are followed.
- From the given set of numbers, the smallest number becomes the divisor, and the larger number becomes the dividend.
- In the next step, the smaller number becomes the dividend, and the remainder becomes the divisor.
- The above step is followed until the remainder is zero.
- The last divisor would be the HCF.
HCF of 3 and 4 by long division method is:
Therefore, HCF (3, 4) = 1
HCF of 3 and 4 by Listing Common Factors
By listing all the factors of given numbers, we can identify the Highest/Greatest/Biggest common factor, which is the HCF. Below is the list of factors for 3 and 4:
Factors of 3: 1 and 3.
Factors of 4: 1, 2 and 4.
Therefore, HCF (3, 4) = 1
