Given numbers are 642, 868, 738, 291

The list of prime factors of all numbers are

Prime factors of 642 are 2 x 3 x 107

Prime factors of 868 are 2 x 2 x 7 x 31

Prime factors of 738 are 2 x 3 x 3 x 41

Prime factors of 291 are 3 x 97

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

Given numbers are 642, 868, 738, 291

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

Apply this formula for all numbers.

Step1:

LCM(642, 868) = 278628

GCD(642, 868) = ( 642 x 868 ) / 278628

= 642 / 868

= 642

Step2:

LCM(2, 738) = 738

GCD(2, 738) = ( 2 x 738 ) / 738

= 2 / 738

= 2

Step3:

LCM(2, 291) = 582

GCD(2, 291) = ( 2 x 291 ) / 582

= 2 / 291

= 2

So, Greatest Common Divisor of 642, 868, 738, 291 is 1
