Given numbers are 915, 688, 757, 456

The list of prime factors of all numbers are

Prime factors of 915 are 3 x 5 x 61

Prime factors of 688 are 2 x 2 x 2 x 2 x 43

Prime factors of 757 are 757

Prime factors of 456 are 2 x 2 x 2 x 3 x 19

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

Given numbers are 915, 688, 757, 456

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

Apply this formula for all numbers.

Step1:

LCM(915, 688) = 629520

GCD(915, 688) = ( 915 x 688 ) / 629520

= 915 / 688

= 915

Step2:

LCM(1, 757) = 757

GCD(1, 757) = ( 1 x 757 ) / 757

= 1 / 757

= 1

Step3:

LCM(1, 456) = 456

GCD(1, 456) = ( 1 x 456 ) / 456

= 1 / 456

= 1

So, Greatest Common Divisor of 915, 688, 757, 456 is 1
