Given numbers are 138, 330, 664, 681

The list of prime factors of all numbers are

Prime factors of 138 are 2 x 3 x 23

Prime factors of 330 are 2 x 3 x 5 x 11

Prime factors of 664 are 2 x 2 x 2 x 83

Prime factors of 681 are 3 x 227

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

Given numbers are 138, 330, 664, 681

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

Apply this formula for all numbers.

Step1:

LCM(138, 330) = 7590

GCD(138, 330) = ( 138 x 330 ) / 7590

= 138 / 330

= 138

Step2:

LCM(6, 664) = 1992

GCD(6, 664) = ( 6 x 664 ) / 1992

= 6 / 664

= 6

Step3:

LCM(2, 681) = 1362

GCD(2, 681) = ( 2 x 681 ) / 1362

= 2 / 681

= 2

So, Greatest Common Divisor of 138, 330, 664, 681 is 1
