Given numbers are 130, 688, 667, 749

The list of prime factors of all numbers are

Prime factors of 130 are 2 x 5 x 13

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

Prime factors of 667 are 23 x 29

Prime factors of 749 are 7 x 107

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

Given numbers are 130, 688, 667, 749

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

Apply this formula for all numbers.

Step1:

LCM(130, 688) = 44720

GCD(130, 688) = ( 130 x 688 ) / 44720

= 130 / 688

= 130

Step2:

LCM(2, 667) = 1334

GCD(2, 667) = ( 2 x 667 ) / 1334

= 2 / 667

= 2

Step3:

LCM(1, 749) = 749

GCD(1, 749) = ( 1 x 749 ) / 749

= 1 / 749

= 1

So, Greatest Common Divisor of 130, 688, 667, 749 is 1
