Given numbers are 287, 298, 187, 672

The list of prime factors of all numbers are

Prime factors of 287 are 7 x 41

Prime factors of 298 are 2 x 149

Prime factors of 187 are 11 x 17

Prime factors of 672 are 2 x 2 x 2 x 2 x 2 x 3 x 7

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

Given numbers are 287, 298, 187, 672

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

Apply this formula for all numbers.

Step1:

LCM(287, 298) = 85526

GCD(287, 298) = ( 287 x 298 ) / 85526

= 287 / 298

= 287

Step2:

LCM(1, 187) = 187

GCD(1, 187) = ( 1 x 187 ) / 187

= 1 / 187

= 1

Step3:

LCM(1, 672) = 672

GCD(1, 672) = ( 1 x 672 ) / 672

= 1 / 672

= 1

So, Greatest Common Divisor of 287, 298, 187, 672 is 1
