Given numbers are 837, 645, 137, 858

The list of prime factors of all numbers are

Prime factors of 837 are 3 x 3 x 3 x 31

Prime factors of 645 are 3 x 5 x 43

Prime factors of 137 are 137

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

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

Given numbers are 837, 645, 137, 858

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

Apply this formula for all numbers.

Step1:

LCM(837, 645) = 179955

GCD(837, 645) = ( 837 x 645 ) / 179955

= 837 / 645

= 837

Step2:

LCM(3, 137) = 411

GCD(3, 137) = ( 3 x 137 ) / 411

= 3 / 137

= 3

Step3:

LCM(1, 858) = 858

GCD(1, 858) = ( 1 x 858 ) / 858

= 1 / 858

= 1

So, Greatest Common Divisor of 837, 645, 137, 858 is 1
