Given numbers are 142, 168, 687, 174

The list of prime factors of all numbers are

Prime factors of 142 are 2 x 71

Prime factors of 168 are 2 x 2 x 2 x 3 x 7

Prime factors of 687 are 3 x 229

Prime factors of 174 are 2 x 3 x 29

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

Given numbers are 142, 168, 687, 174

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

Apply this formula for all numbers.

Step1:

LCM(142, 168) = 11928

GCD(142, 168) = ( 142 x 168 ) / 11928

= 142 / 168

= 142

Step2:

LCM(2, 687) = 1374

GCD(2, 687) = ( 2 x 687 ) / 1374

= 2 / 687

= 2

Step3:

LCM(1, 174) = 174

GCD(1, 174) = ( 1 x 174 ) / 174

= 1 / 174

= 1

So, Greatest Common Divisor of 142, 168, 687, 174 is 1
