Given numbers are 391, 286, 357, 684

The list of prime factors of all numbers are

Prime factors of 391 are 17 x 23

Prime factors of 286 are 2 x 11 x 13

Prime factors of 357 are 3 x 7 x 17

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

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

Given numbers are 391, 286, 357, 684

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

Apply this formula for all numbers.

Step1:

LCM(391, 286) = 111826

GCD(391, 286) = ( 391 x 286 ) / 111826

= 391 / 286

= 391

Step2:

LCM(1, 357) = 357

GCD(1, 357) = ( 1 x 357 ) / 357

= 1 / 357

= 1

Step3:

LCM(1, 684) = 684

GCD(1, 684) = ( 1 x 684 ) / 684

= 1 / 684

= 1

So, Greatest Common Divisor of 391, 286, 357, 684 is 1
