Given numbers are 287, 308, 120, 915

The list of prime factors of all numbers are

Prime factors of 287 are 7 x 41

Prime factors of 308 are 2 x 2 x 7 x 11

Prime factors of 120 are 2 x 2 x 2 x 3 x 5

Prime factors of 915 are 3 x 5 x 61

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

Given numbers are 287, 308, 120, 915

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

Apply this formula for all numbers.

Step1:

LCM(287, 308) = 12628

GCD(287, 308) = ( 287 x 308 ) / 12628

= 287 / 308

= 287

Step2:

LCM(7, 120) = 840

GCD(7, 120) = ( 7 x 120 ) / 840

= 7 / 120

= 7

Step3:

LCM(1, 915) = 915

GCD(1, 915) = ( 1 x 915 ) / 915

= 1 / 915

= 1

So, Greatest Common Divisor of 287, 308, 120, 915 is 1
