Greatest Common Divisior

We found the divisors of 72, 62, 57 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 72, 62, 57 is 1.

Therefore, GCD of numbers 72, 62, 57 is 1

Given Input Data is 72, 62, 57

Make a list of Prime Factors of all the given numbers initially

Prime Factorization of 72 is 2 x 2 x 2 x 3 x 3

Prime Factorization of 62 is 2 x 31

Prime Factorization of 57 is 3 x 19

The above numbers do not have any common prime factor. So GCD is 1

Step1:

Let's calculate the GCD of first two numbers

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(72, 62) = 2232

GCD(72, 62) = ( 72 x 62 ) / 2232

GCD(72, 62) = 4464 / 2232

GCD(72, 62) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 57

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(2, 57) = 114

GCD(2, 57) = ( 2 x 57 ) / 114

GCD(2, 57) = 114 / 114

GCD(2, 57) = 1

GCD of 72, 62, 57 is 1
