Given numbers are 644, 546, 259, 657

The list of prime factors of all numbers are

Prime factors of 644 are 2 x 2 x 7 x 23

Prime factors of 546 are 2 x 3 x 7 x 13

Prime factors of 259 are 7 x 37

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 644, 546, 259, 657

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

Apply this formula for all numbers.

Step1:

LCM(644, 546) = 25116

GCD(644, 546) = ( 644 x 546 ) / 25116

= 644 / 546

= 644

Step2:

LCM(14, 259) = 518

GCD(14, 259) = ( 14 x 259 ) / 518

= 14 / 259

= 14

Step3:

LCM(7, 657) = 4599

GCD(7, 657) = ( 7 x 657 ) / 4599

= 7 / 657

= 7

So, Greatest Common Divisor of 644, 546, 259, 657 is 1
