Given numbers are 399, 631, 136, 164

The list of prime factors of all numbers are

Prime factors of 399 are 3 x 7 x 19

Prime factors of 631 are 631

Prime factors of 136 are 2 x 2 x 2 x 17

Prime factors of 164 are 2 x 2 x 41

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

Given numbers are 399, 631, 136, 164

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

Apply this formula for all numbers.

Step1:

LCM(399, 631) = 251769

GCD(399, 631) = ( 399 x 631 ) / 251769

= 399 / 631

= 399

Step2:

LCM(1, 136) = 136

GCD(1, 136) = ( 1 x 136 ) / 136

= 1 / 136

= 1

Step3:

LCM(1, 164) = 164

GCD(1, 164) = ( 1 x 164 ) / 164

= 1 / 164

= 1

So, Greatest Common Divisor of 399, 631, 136, 164 is 1
