Given numbers are 915, 205, 505, 972

The list of prime factors of all numbers are

Prime factors of 915 are 3 x 5 x 61

Prime factors of 205 are 5 x 41

Prime factors of 505 are 5 x 101

Prime factors of 972 are 2 x 2 x 3 x 3 x 3 x 3 x 3

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

Given numbers are 915, 205, 505, 972

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

Apply this formula for all numbers.

Step1:

LCM(915, 205) = 37515

GCD(915, 205) = ( 915 x 205 ) / 37515

= 915 / 205

= 915

Step2:

LCM(5, 505) = 505

GCD(5, 505) = ( 5 x 505 ) / 505

= 5 / 505

= 5

Step3:

LCM(5, 972) = 4860

GCD(5, 972) = ( 5 x 972 ) / 4860

= 5 / 972

= 5

So, Greatest Common Divisor of 915, 205, 505, 972 is 1
