Given numbers are 427, 615, 687, 280

The list of prime factors of all numbers are

Prime factors of 427 are 7 x 61

Prime factors of 615 are 3 x 5 x 41

Prime factors of 687 are 3 x 229

Prime factors of 280 are 2 x 2 x 2 x 5 x 7

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

Given numbers are 427, 615, 687, 280

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

Apply this formula for all numbers.

Step1:

LCM(427, 615) = 262605

GCD(427, 615) = ( 427 x 615 ) / 262605

= 427 / 615

= 427

Step2:

LCM(1, 687) = 687

GCD(1, 687) = ( 1 x 687 ) / 687

= 1 / 687

= 1

Step3:

LCM(1, 280) = 280

GCD(1, 280) = ( 1 x 280 ) / 280

= 1 / 280

= 1

So, Greatest Common Divisor of 427, 615, 687, 280 is 1
