Given numbers are 385, 651, 164, 668

The list of prime factors of all numbers are

Prime factors of 385 are 5 x 7 x 11

Prime factors of 651 are 3 x 7 x 31

Prime factors of 164 are 2 x 2 x 41

Prime factors of 668 are 2 x 2 x 167

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

Given numbers are 385, 651, 164, 668

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

Apply this formula for all numbers.

Step1:

LCM(385, 651) = 35805

GCD(385, 651) = ( 385 x 651 ) / 35805

= 385 / 651

= 385

Step2:

LCM(7, 164) = 1148

GCD(7, 164) = ( 7 x 164 ) / 1148

= 7 / 164

= 7

Step3:

LCM(1, 668) = 668

GCD(1, 668) = ( 1 x 668 ) / 668

= 1 / 668

= 1

So, Greatest Common Divisor of 385, 651, 164, 668 is 1
