Given numbers are 915, 110, 664, 645

The list of prime factors of all numbers are

Prime factors of 915 are 3 x 5 x 61

Prime factors of 110 are 2 x 5 x 11

Prime factors of 664 are 2 x 2 x 2 x 83

Prime factors of 645 are 3 x 5 x 43

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

Given numbers are 915, 110, 664, 645

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

Apply this formula for all numbers.

Step1:

LCM(915, 110) = 20130

GCD(915, 110) = ( 915 x 110 ) / 20130

= 915 / 110

= 915

Step2:

LCM(5, 664) = 3320

GCD(5, 664) = ( 5 x 664 ) / 3320

= 5 / 664

= 5

Step3:

LCM(1, 645) = 645

GCD(1, 645) = ( 1 x 645 ) / 645

= 1 / 645

= 1

So, Greatest Common Divisor of 915, 110, 664, 645 is 1
