Given numbers are 138, 211, 870, 392

The list of prime factors of all numbers are

Prime factors of 138 are 2 x 3 x 23

Prime factors of 211 are 211

Prime factors of 870 are 2 x 3 x 5 x 29

Prime factors of 392 are 2 x 2 x 2 x 7 x 7

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

Given numbers are 138, 211, 870, 392

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

Apply this formula for all numbers.

Step1:

LCM(138, 211) = 29118

GCD(138, 211) = ( 138 x 211 ) / 29118

= 138 / 211

= 138

Step2:

LCM(1, 870) = 870

GCD(1, 870) = ( 1 x 870 ) / 870

= 1 / 870

= 1

Step3:

LCM(1, 392) = 392

GCD(1, 392) = ( 1 x 392 ) / 392

= 1 / 392

= 1

So, Greatest Common Divisor of 138, 211, 870, 392 is 1
