Given numbers are 422, 851, 842, 813

The list of prime factors of all numbers are

Prime factors of 422 are 2 x 211

Prime factors of 851 are 23 x 37

Prime factors of 842 are 2 x 421

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 422, 851, 842, 813

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

Apply this formula for all numbers.

Step1:

LCM(422, 851) = 359122

GCD(422, 851) = ( 422 x 851 ) / 359122

= 422 / 851

= 422

Step2:

LCM(1, 842) = 842

GCD(1, 842) = ( 1 x 842 ) / 842

= 1 / 842

= 1

Step3:

LCM(1, 813) = 813

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

= 1 / 813

= 1

So, Greatest Common Divisor of 422, 851, 842, 813 is 1
