Given numbers are 852, 138, 397, 680

The list of prime factors of all numbers are

Prime factors of 852 are 2 x 2 x 3 x 71

Prime factors of 138 are 2 x 3 x 23

Prime factors of 397 are 397

Prime factors of 680 are 2 x 2 x 2 x 5 x 17

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

Given numbers are 852, 138, 397, 680

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

Apply this formula for all numbers.

Step1:

LCM(852, 138) = 19596

GCD(852, 138) = ( 852 x 138 ) / 19596

= 852 / 138

= 852

Step2:

LCM(6, 397) = 2382

GCD(6, 397) = ( 6 x 397 ) / 2382

= 6 / 397

= 6

Step3:

LCM(1, 680) = 680

GCD(1, 680) = ( 1 x 680 ) / 680

= 1 / 680

= 1

So, Greatest Common Divisor of 852, 138, 397, 680 is 1
