Given numbers are 280, 615, 684, 493

The list of prime factors of all numbers are

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

Prime factors of 615 are 3 x 5 x 41

Prime factors of 684 are 2 x 2 x 3 x 3 x 19

Prime factors of 493 are 17 x 29

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

Given numbers are 280, 615, 684, 493

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

Apply this formula for all numbers.

Step1:

LCM(280, 615) = 34440

GCD(280, 615) = ( 280 x 615 ) / 34440

= 280 / 615

= 280

Step2:

LCM(5, 684) = 3420

GCD(5, 684) = ( 5 x 684 ) / 3420

= 5 / 684

= 5

Step3:

LCM(1, 493) = 493

GCD(1, 493) = ( 1 x 493 ) / 493

= 1 / 493

= 1

So, Greatest Common Divisor of 280, 615, 684, 493 is 1
