Given numbers are 646, 511, 668, 185

The list of prime factors of all numbers are

Prime factors of 646 are 2 x 17 x 19

Prime factors of 511 are 7 x 73

Prime factors of 668 are 2 x 2 x 167

Prime factors of 185 are 5 x 37

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

Given numbers are 646, 511, 668, 185

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

Apply this formula for all numbers.

Step1:

LCM(646, 511) = 330106

GCD(646, 511) = ( 646 x 511 ) / 330106

= 646 / 511

= 646

Step2:

LCM(1, 668) = 668

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

= 1 / 668

= 1

Step3:

LCM(1, 185) = 185

GCD(1, 185) = ( 1 x 185 ) / 185

= 1 / 185

= 1

So, Greatest Common Divisor of 646, 511, 668, 185 is 1
