Given numbers are 688, 494, 485, 126

The list of prime factors of all numbers are

Prime factors of 688 are 2 x 2 x 2 x 2 x 43

Prime factors of 494 are 2 x 13 x 19

Prime factors of 485 are 5 x 97

Prime factors of 126 are 2 x 3 x 3 x 7

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

Given numbers are 688, 494, 485, 126

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

Apply this formula for all numbers.

Step1:

LCM(688, 494) = 169936

GCD(688, 494) = ( 688 x 494 ) / 169936

= 688 / 494

= 688

Step2:

LCM(2, 485) = 970

GCD(2, 485) = ( 2 x 485 ) / 970

= 2 / 485

= 2

Step3:

LCM(1, 126) = 126

GCD(1, 126) = ( 1 x 126 ) / 126

= 1 / 126

= 1

So, Greatest Common Divisor of 688, 494, 485, 126 is 1
