Given numbers are 756, 321, 702, 653

The list of prime factors of all numbers are

Prime factors of 756 are 2 x 2 x 3 x 3 x 3 x 7

Prime factors of 321 are 3 x 107

Prime factors of 702 are 2 x 3 x 3 x 3 x 13

Prime factors of 653 are 653

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

Given numbers are 756, 321, 702, 653

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(756, 321) = 80892

GCD(756, 321) = ( 756 x 321 ) / 80892

= 756 / 321

= 756

Step2:

LCM(3, 702) = 702

GCD(3, 702) = ( 3 x 702 ) / 702

= 3 / 702

= 3

Step3:

LCM(3, 653) = 1959

GCD(3, 653) = ( 3 x 653 ) / 1959

= 3 / 653

= 3

So, Greatest Common Divisor of 756, 321, 702, 653 is 1
