Given numbers are 126, 681, 728, 130

The list of prime factors of all numbers are

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

Prime factors of 681 are 3 x 227

Prime factors of 728 are 2 x 2 x 2 x 7 x 13

Prime factors of 130 are 2 x 5 x 13

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

Given numbers are 126, 681, 728, 130

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

Apply this formula for all numbers.

Step1:

LCM(126, 681) = 28602

GCD(126, 681) = ( 126 x 681 ) / 28602

= 126 / 681

= 126

Step2:

LCM(3, 728) = 2184

GCD(3, 728) = ( 3 x 728 ) / 2184

= 3 / 728

= 3

Step3:

LCM(1, 130) = 130

GCD(1, 130) = ( 1 x 130 ) / 130

= 1 / 130

= 1

So, Greatest Common Divisor of 126, 681, 728, 130 is 1
