Given numbers are 317, 840, 164, 813

The list of prime factors of all numbers are

Prime factors of 317 are 317

Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7

Prime factors of 164 are 2 x 2 x 41

Prime factors of 813 are 3 x 271

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

Given numbers are 317, 840, 164, 813

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

Apply this formula for all numbers.

Step1:

LCM(317, 840) = 266280

GCD(317, 840) = ( 317 x 840 ) / 266280

= 317 / 840

= 317

Step2:

LCM(1, 164) = 164

GCD(1, 164) = ( 1 x 164 ) / 164

= 1 / 164

= 1

Step3:

LCM(1, 813) = 813

GCD(1, 813) = ( 1 x 813 ) / 813

= 1 / 813

= 1

So, Greatest Common Divisor of 317, 840, 164, 813 is 1
