Given numbers are 915, 420, 288, 100

The list of prime factors of all numbers are

Prime factors of 915 are 3 x 5 x 61

Prime factors of 420 are 2 x 2 x 3 x 5 x 7

Prime factors of 288 are 2 x 2 x 2 x 2 x 2 x 3 x 3

Prime factors of 100 are 2 x 2 x 5 x 5

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

Given numbers are 915, 420, 288, 100

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

Apply this formula for all numbers.

Step1:

LCM(915, 420) = 25620

GCD(915, 420) = ( 915 x 420 ) / 25620

= 915 / 420

= 915

Step2:

LCM(15, 288) = 1440

GCD(15, 288) = ( 15 x 288 ) / 1440

= 15 / 288

= 15

Step3:

LCM(3, 100) = 300

GCD(3, 100) = ( 3 x 100 ) / 300

= 3 / 100

= 3

So, Greatest Common Divisor of 915, 420, 288, 100 is 1
