Given numbers are 133, 164, 656, 390

The list of prime factors of all numbers are

Prime factors of 133 are 7 x 19

Prime factors of 164 are 2 x 2 x 41

Prime factors of 656 are 2 x 2 x 2 x 2 x 41

Prime factors of 390 are 2 x 3 x 5 x 13

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

Given numbers are 133, 164, 656, 390

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

Apply this formula for all numbers.

Step1:

LCM(133, 164) = 21812

GCD(133, 164) = ( 133 x 164 ) / 21812

= 133 / 164

= 133

Step2:

LCM(1, 656) = 656

GCD(1, 656) = ( 1 x 656 ) / 656

= 1 / 656

= 1

Step3:

LCM(1, 390) = 390

GCD(1, 390) = ( 1 x 390 ) / 390

= 1 / 390

= 1

So, Greatest Common Divisor of 133, 164, 656, 390 is 1
