Given numbers are 668, 130, 138, 671

The list of prime factors of all numbers are

Prime factors of 668 are 2 x 2 x 167

Prime factors of 130 are 2 x 5 x 13

Prime factors of 138 are 2 x 3 x 23

Prime factors of 671 are 11 x 61

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

Given numbers are 668, 130, 138, 671

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

Apply this formula for all numbers.

Step1:

LCM(668, 130) = 43420

GCD(668, 130) = ( 668 x 130 ) / 43420

= 668 / 130

= 668

Step2:

LCM(2, 138) = 138

GCD(2, 138) = ( 2 x 138 ) / 138

= 2 / 138

= 2

Step3:

LCM(2, 671) = 1342

GCD(2, 671) = ( 2 x 671 ) / 1342

= 2 / 671

= 2

So, Greatest Common Divisor of 668, 130, 138, 671 is 1
