Given numbers are 130, 470, 657, 672

The list of prime factors of all numbers are

Prime factors of 130 are 2 x 5 x 13

Prime factors of 470 are 2 x 5 x 47

Prime factors of 657 are 3 x 3 x 73

Prime factors of 672 are 2 x 2 x 2 x 2 x 2 x 3 x 7

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

Given numbers are 130, 470, 657, 672

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

Apply this formula for all numbers.

Step1:

LCM(130, 470) = 6110

GCD(130, 470) = ( 130 x 470 ) / 6110

= 130 / 470

= 130

Step2:

LCM(10, 657) = 6570

GCD(10, 657) = ( 10 x 657 ) / 6570

= 10 / 657

= 10

Step3:

LCM(1, 672) = 672

GCD(1, 672) = ( 1 x 672 ) / 672

= 1 / 672

= 1

So, Greatest Common Divisor of 130, 470, 657, 672 is 1
