Given numbers are 286, 310, 65, 665

The list of prime factors of all numbers are

Prime factors of 286 are 2 x 11 x 13

Prime factors of 310 are 2 x 5 x 31

Prime factors of 65 are 5 x 13

Prime factors of 665 are 5 x 7 x 19

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

Given numbers are 286, 310, 65, 665

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

Apply this formula for all numbers.

Step1:

LCM(286, 310) = 44330

GCD(286, 310) = ( 286 x 310 ) / 44330

= 286 / 310

= 286

Step2:

LCM(2, 65) = 130

GCD(2, 65) = ( 2 x 65 ) / 130

= 2 / 65

= 2

Step3:

LCM(1, 665) = 665

GCD(1, 665) = ( 1 x 665 ) / 665

= 1 / 665

= 1

So, Greatest Common Divisor of 286, 310, 65, 665 is 1
