Given numbers are 138, 659, 612, 212

The list of prime factors of all numbers are

Prime factors of 138 are 2 x 3 x 23

Prime factors of 659 are 659

Prime factors of 612 are 2 x 2 x 3 x 3 x 17

Prime factors of 212 are 2 x 2 x 53

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

Given numbers are 138, 659, 612, 212

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

Apply this formula for all numbers.

Step1:

LCM(138, 659) = 90942

GCD(138, 659) = ( 138 x 659 ) / 90942

= 138 / 659

= 138

Step2:

LCM(1, 612) = 612

GCD(1, 612) = ( 1 x 612 ) / 612

= 1 / 612

= 1

Step3:

LCM(1, 212) = 212

GCD(1, 212) = ( 1 x 212 ) / 212

= 1 / 212

= 1

So, Greatest Common Divisor of 138, 659, 612, 212 is 1
