Given numbers are 657, 668, 648, 682

The list of prime factors of all numbers are

Prime factors of 657 are 3 x 3 x 73

Prime factors of 668 are 2 x 2 x 167

Prime factors of 648 are 2 x 2 x 2 x 3 x 3 x 3 x 3

Prime factors of 682 are 2 x 11 x 31

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

Given numbers are 657, 668, 648, 682

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

Apply this formula for all numbers.

Step1:

LCM(657, 668) = 438876

GCD(657, 668) = ( 657 x 668 ) / 438876

= 657 / 668

= 657

Step2:

LCM(1, 648) = 648

GCD(1, 648) = ( 1 x 648 ) / 648

= 1 / 648

= 1

Step3:

LCM(1, 682) = 682

GCD(1, 682) = ( 1 x 682 ) / 682

= 1 / 682

= 1

So, Greatest Common Divisor of 657, 668, 648, 682 is 1
