Given numbers are 138, 637, 700, 426

The list of prime factors of all numbers are

Prime factors of 138 are 2 x 3 x 23

Prime factors of 637 are 7 x 7 x 13

Prime factors of 700 are 2 x 2 x 5 x 5 x 7

Prime factors of 426 are 2 x 3 x 71

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

Given numbers are 138, 637, 700, 426

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

Apply this formula for all numbers.

Step1:

LCM(138, 637) = 87906

GCD(138, 637) = ( 138 x 637 ) / 87906

= 138 / 637

= 138

Step2:

LCM(1, 700) = 700

GCD(1, 700) = ( 1 x 700 ) / 700

= 1 / 700

= 1

Step3:

LCM(1, 426) = 426

GCD(1, 426) = ( 1 x 426 ) / 426

= 1 / 426

= 1

So, Greatest Common Divisor of 138, 637, 700, 426 is 1
