Given numbers are 642, 936, 142, 347

The list of prime factors of all numbers are

Prime factors of 642 are 2 x 3 x 107

Prime factors of 936 are 2 x 2 x 2 x 3 x 3 x 13

Prime factors of 142 are 2 x 71

Prime factors of 347 are 347

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

Given numbers are 642, 936, 142, 347

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

Apply this formula for all numbers.

Step1:

LCM(642, 936) = 100152

GCD(642, 936) = ( 642 x 936 ) / 100152

= 642 / 936

= 642

Step2:

LCM(6, 142) = 426

GCD(6, 142) = ( 6 x 142 ) / 426

= 6 / 142

= 6

Step3:

LCM(2, 347) = 694

GCD(2, 347) = ( 2 x 347 ) / 694

= 2 / 347

= 2

So, Greatest Common Divisor of 642, 936, 142, 347 is 1
