Given numbers are 642, 407, 858, 774

The list of prime factors of all numbers are

Prime factors of 642 are 2 x 3 x 107

Prime factors of 407 are 11 x 37

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

Prime factors of 774 are 2 x 3 x 3 x 43

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

Given numbers are 642, 407, 858, 774

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

Apply this formula for all numbers.

Step1:

LCM(642, 407) = 261294

GCD(642, 407) = ( 642 x 407 ) / 261294

= 642 / 407

= 642

Step2:

LCM(1, 858) = 858

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

= 1 / 858

= 1

Step3:

LCM(1, 774) = 774

GCD(1, 774) = ( 1 x 774 ) / 774

= 1 / 774

= 1

So, Greatest Common Divisor of 642, 407, 858, 774 is 1
