Given numbers are 771, 855, 574, 137

The list of prime factors of all numbers are

Prime factors of 771 are 3 x 257

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

Prime factors of 574 are 2 x 7 x 41

Prime factors of 137 are 137

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

Given numbers are 771, 855, 574, 137

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

Apply this formula for all numbers.

Step1:

LCM(771, 855) = 219735

GCD(771, 855) = ( 771 x 855 ) / 219735

= 771 / 855

= 771

Step2:

LCM(3, 574) = 1722

GCD(3, 574) = ( 3 x 574 ) / 1722

= 3 / 574

= 3

Step3:

LCM(1, 137) = 137

GCD(1, 137) = ( 1 x 137 ) / 137

= 1 / 137

= 1

So, Greatest Common Divisor of 771, 855, 574, 137 is 1
