Given numbers are 298, 564, 287, 644

The list of prime factors of all numbers are

Prime factors of 298 are 2 x 149

Prime factors of 564 are 2 x 2 x 3 x 47

Prime factors of 287 are 7 x 41

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

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

Given numbers are 298, 564, 287, 644

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

Apply this formula for all numbers.

Step1:

LCM(298, 564) = 84036

GCD(298, 564) = ( 298 x 564 ) / 84036

= 298 / 564

= 298

Step2:

LCM(2, 287) = 574

GCD(2, 287) = ( 2 x 287 ) / 574

= 2 / 287

= 2

Step3:

LCM(1, 644) = 644

GCD(1, 644) = ( 1 x 644 ) / 644

= 1 / 644

= 1

So, Greatest Common Divisor of 298, 564, 287, 644 is 1
