Given numbers are 845, 480, 312, 686

The list of prime factors of all numbers are

Prime factors of 845 are 5 x 13 x 13

Prime factors of 480 are 2 x 2 x 2 x 2 x 2 x 3 x 5

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

Prime factors of 686 are 2 x 7 x 7 x 7

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

Given numbers are 845, 480, 312, 686

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

Apply this formula for all numbers.

Step1:

LCM(845, 480) = 81120

GCD(845, 480) = ( 845 x 480 ) / 81120

= 845 / 480

= 845

Step2:

LCM(5, 312) = 1560

GCD(5, 312) = ( 5 x 312 ) / 1560

= 5 / 312

= 5

Step3:

LCM(1, 686) = 686

GCD(1, 686) = ( 1 x 686 ) / 686

= 1 / 686

= 1

So, Greatest Common Divisor of 845, 480, 312, 686 is 1
