Given numbers are 645, 473, 258, 657

The list of prime factors of all numbers are

Prime factors of 645 are 3 x 5 x 43

Prime factors of 473 are 11 x 43

Prime factors of 258 are 2 x 3 x 43

Prime factors of 657 are 3 x 3 x 73

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

Given numbers are 645, 473, 258, 657

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

Apply this formula for all numbers.

Step1:

LCM(645, 473) = 7095

GCD(645, 473) = ( 645 x 473 ) / 7095

= 645 / 473

= 645

Step2:

LCM(43, 258) = 258

GCD(43, 258) = ( 43 x 258 ) / 258

= 43 / 258

= 43

Step3:

LCM(43, 657) = 28251

GCD(43, 657) = ( 43 x 657 ) / 28251

= 43 / 657

= 43

So, Greatest Common Divisor of 645, 473, 258, 657 is 1
