Given numbers are 399, 287, 756, 254

The list of prime factors of all numbers are

Prime factors of 399 are 3 x 7 x 19

Prime factors of 287 are 7 x 41

Prime factors of 756 are 2 x 2 x 3 x 3 x 3 x 7

Prime factors of 254 are 2 x 127

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

Given numbers are 399, 287, 756, 254

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

Apply this formula for all numbers.

Step1:

LCM(399, 287) = 16359

GCD(399, 287) = ( 399 x 287 ) / 16359

= 399 / 287

= 399

Step2:

LCM(7, 756) = 756

GCD(7, 756) = ( 7 x 756 ) / 756

= 7 / 756

= 7

Step3:

LCM(7, 254) = 1778

GCD(7, 254) = ( 7 x 254 ) / 1778

= 7 / 254

= 7

So, Greatest Common Divisor of 399, 287, 756, 254 is 1
