Given numbers are 855, 651, 38

The list of prime factors of all numbers are

Prime factors of 855 are 3 x 3 x 5 x 19

Prime factors of 651 are 3 x 7 x 31

Prime factors of 38 are 2 x 19

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

Given numbers are 855, 651, 38

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

Apply this formula for all numbers.

Step1:

LCM(855, 651) = 185535

GCD(855, 651) = ( 855 x 651 ) / 185535

= 855 / 651

= 855

Step2:

LCM(3, 38) = 114

GCD(3, 38) = ( 3 x 38 ) / 114

= 3 / 38

= 3

So, Greatest Common Divisor of 855, 651, 38 is 1
