Given numbers are 915, 416, 691, 640

The list of prime factors of all numbers are

Prime factors of 915 are 3 x 5 x 61

Prime factors of 416 are 2 x 2 x 2 x 2 x 2 x 13

Prime factors of 691 are 691

Prime factors of 640 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 5

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

Given numbers are 915, 416, 691, 640

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

Apply this formula for all numbers.

Step1:

LCM(915, 416) = 380640

GCD(915, 416) = ( 915 x 416 ) / 380640

= 915 / 416

= 915

Step2:

LCM(1, 691) = 691

GCD(1, 691) = ( 1 x 691 ) / 691

= 1 / 691

= 1

Step3:

LCM(1, 640) = 640

GCD(1, 640) = ( 1 x 640 ) / 640

= 1 / 640

= 1

So, Greatest Common Divisor of 915, 416, 691, 640 is 1
