Given numbers are 680, 480, 468, 129

The list of prime factors of all numbers are

Prime factors of 680 are 2 x 2 x 2 x 5 x 17

Prime factors of 480 are 2 x 2 x 2 x 2 x 2 x 3 x 5

Prime factors of 468 are 2 x 2 x 3 x 3 x 13

Prime factors of 129 are 3 x 43

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

Given numbers are 680, 480, 468, 129

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

Apply this formula for all numbers.

Step1:

LCM(680, 480) = 8160

GCD(680, 480) = ( 680 x 480 ) / 8160

= 680 / 480

= 680

Step2:

LCM(40, 468) = 4680

GCD(40, 468) = ( 40 x 468 ) / 4680

= 40 / 468

= 40

Step3:

LCM(4, 129) = 516

GCD(4, 129) = ( 4 x 129 ) / 516

= 4 / 129

= 4

So, Greatest Common Divisor of 680, 480, 468, 129 is 1
