Given numbers are 616, 858, 798, 815

The list of prime factors of all numbers are

Prime factors of 616 are 2 x 2 x 2 x 7 x 11

Prime factors of 858 are 2 x 3 x 11 x 13

Prime factors of 798 are 2 x 3 x 7 x 19

Prime factors of 815 are 5 x 163

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

Given numbers are 616, 858, 798, 815

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

Apply this formula for all numbers.

Step1:

LCM(616, 858) = 24024

GCD(616, 858) = ( 616 x 858 ) / 24024

= 616 / 858

= 616

Step2:

LCM(22, 798) = 8778

GCD(22, 798) = ( 22 x 798 ) / 8778

= 22 / 798

= 22

Step3:

LCM(2, 815) = 1630

GCD(2, 815) = ( 2 x 815 ) / 1630

= 2 / 815

= 2

So, Greatest Common Divisor of 616, 858, 798, 815 is 1
