Given numbers are 427, 858, 855, 574

The list of prime factors of all numbers are

Prime factors of 427 are 7 x 61

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

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

Prime factors of 574 are 2 x 7 x 41

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

Given numbers are 427, 858, 855, 574

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

Apply this formula for all numbers.

Step1:

LCM(427, 858) = 366366

GCD(427, 858) = ( 427 x 858 ) / 366366

= 427 / 858

= 427

Step2:

LCM(1, 855) = 855

GCD(1, 855) = ( 1 x 855 ) / 855

= 1 / 855

= 1

Step3:

LCM(1, 574) = 574

GCD(1, 574) = ( 1 x 574 ) / 574

= 1 / 574

= 1

So, Greatest Common Divisor of 427, 858, 855, 574 is 1
