Given numbers are 684, 490, 864, 631

The list of prime factors of all numbers are

Prime factors of 684 are 2 x 2 x 3 x 3 x 19

Prime factors of 490 are 2 x 5 x 7 x 7

Prime factors of 864 are 2 x 2 x 2 x 2 x 2 x 3 x 3 x 3

Prime factors of 631 are 631

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

Given numbers are 684, 490, 864, 631

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

Apply this formula for all numbers.

Step1:

LCM(684, 490) = 167580

GCD(684, 490) = ( 684 x 490 ) / 167580

= 684 / 490

= 684

Step2:

LCM(2, 864) = 864

GCD(2, 864) = ( 2 x 864 ) / 864

= 2 / 864

= 2

Step3:

LCM(2, 631) = 1262

GCD(2, 631) = ( 2 x 631 ) / 1262

= 2 / 631

= 2

So, Greatest Common Divisor of 684, 490, 864, 631 is 1
