Given numbers are 915, 400, 613, 872

The list of prime factors of all numbers are

Prime factors of 915 are 3 x 5 x 61

Prime factors of 400 are 2 x 2 x 2 x 2 x 5 x 5

Prime factors of 613 are 613

Prime factors of 872 are 2 x 2 x 2 x 109

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

Given numbers are 915, 400, 613, 872

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

Apply this formula for all numbers.

Step1:

LCM(915, 400) = 73200

GCD(915, 400) = ( 915 x 400 ) / 73200

= 915 / 400

= 915

Step2:

LCM(5, 613) = 3065

GCD(5, 613) = ( 5 x 613 ) / 3065

= 5 / 613

= 5

Step3:

LCM(1, 872) = 872

GCD(1, 872) = ( 1 x 872 ) / 872

= 1 / 872

= 1

So, Greatest Common Divisor of 915, 400, 613, 872 is 1
