Given numbers are 137, 143, 685, 142

The list of prime factors of all numbers are

Prime factors of 137 are 137

Prime factors of 143 are 11 x 13

Prime factors of 685 are 5 x 137

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 137, 143, 685, 142

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

Apply this formula for all numbers.

Step1:

LCM(137, 143) = 19591

GCD(137, 143) = ( 137 x 143 ) / 19591

= 137 / 143

= 137

Step2:

LCM(1, 685) = 685

GCD(1, 685) = ( 1 x 685 ) / 685

= 1 / 685

= 1

Step3:

LCM(1, 142) = 142

GCD(1, 142) = ( 1 x 142 ) / 142

= 1 / 142

= 1

So, Greatest Common Divisor of 137, 143, 685, 142 is 1
