Given numbers are 415, 687, 316, 156

The list of prime factors of all numbers are

Prime factors of 415 are 5 x 83

Prime factors of 687 are 3 x 229

Prime factors of 316 are 2 x 2 x 79

Prime factors of 156 are 2 x 2 x 3 x 13

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

Given numbers are 415, 687, 316, 156

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

Apply this formula for all numbers.

Step1:

LCM(415, 687) = 285105

GCD(415, 687) = ( 415 x 687 ) / 285105

= 415 / 687

= 415

Step2:

LCM(1, 316) = 316

GCD(1, 316) = ( 1 x 316 ) / 316

= 1 / 316

= 1

Step3:

LCM(1, 156) = 156

GCD(1, 156) = ( 1 x 156 ) / 156

= 1 / 156

= 1

So, Greatest Common Divisor of 415, 687, 316, 156 is 1
