Given numbers are 915, 225, 123, 307

The list of prime factors of all numbers are

Prime factors of 915 are 3 x 5 x 61

Prime factors of 225 are 3 x 3 x 5 x 5

Prime factors of 123 are 3 x 41

Prime factors of 307 are 307

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

Given numbers are 915, 225, 123, 307

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

Apply this formula for all numbers.

Step1:

LCM(915, 225) = 13725

GCD(915, 225) = ( 915 x 225 ) / 13725

= 915 / 225

= 915

Step2:

LCM(15, 123) = 615

GCD(15, 123) = ( 15 x 123 ) / 615

= 15 / 123

= 15

Step3:

LCM(3, 307) = 921

GCD(3, 307) = ( 3 x 307 ) / 921

= 3 / 307

= 3

So, Greatest Common Divisor of 915, 225, 123, 307 is 1
