Given numbers are 642, 454, 855, 334

The list of prime factors of all numbers are

Prime factors of 642 are 2 x 3 x 107

Prime factors of 454 are 2 x 227

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

Prime factors of 334 are 2 x 167

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

Given numbers are 642, 454, 855, 334

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

Apply this formula for all numbers.

Step1:

LCM(642, 454) = 145734

GCD(642, 454) = ( 642 x 454 ) / 145734

= 642 / 454

= 642

Step2:

LCM(2, 855) = 1710

GCD(2, 855) = ( 2 x 855 ) / 1710

= 2 / 855

= 2

Step3:

LCM(1, 334) = 334

GCD(1, 334) = ( 1 x 334 ) / 334

= 1 / 334

= 1

So, Greatest Common Divisor of 642, 454, 855, 334 is 1
