The list of prime factors of all numbers are

Prime factors of 687 are 3 x 229

Prime factors of 606 are 2 x 3 x 101

Prime factors of 903 are 3 x 7 x 43

Prime factors of 142 are 2 x 71

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

Given numbers are 687, 606, 903, 142

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

Apply this formula for all numbers.

Step1:

LCM(687, 606) = 138774

GCD(687, 606) = ( 687 x 606 ) / 138774

= 687 / 606

= 687

Step2:

LCM(3, 903) = 903

GCD(3, 903) = ( 3 x 903 ) / 903

= 3 / 903

= 3

Step3:

LCM(3, 142) = 426

GCD(3, 142) = ( 3 x 142 ) / 426

= 3 / 142

= 3

So, Greatest Common Divisor of 687, 606, 903, 142 is 1
