Given numbers are 286, 815, 357, 312

The list of prime factors of all numbers are

Prime factors of 286 are 2 x 11 x 13

Prime factors of 815 are 5 x 163

Prime factors of 357 are 3 x 7 x 17

Prime factors of 312 are 2 x 2 x 2 x 3 x 13

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

Given numbers are 286, 815, 357, 312

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

Apply this formula for all numbers.

Step1:

LCM(286, 815) = 233090

GCD(286, 815) = ( 286 x 815 ) / 233090

= 286 / 815

= 286

Step2:

LCM(1, 357) = 357

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

= 1 / 357

= 1

Step3:

LCM(1, 312) = 312

GCD(1, 312) = ( 1 x 312 ) / 312

= 1 / 312

= 1

So, Greatest Common Divisor of 286, 815, 357, 312 is 1
