Given numbers are 142, 169, 870, 168

The list of prime factors of all numbers are

Prime factors of 142 are 2 x 71

Prime factors of 169 are 13 x 13

Prime factors of 870 are 2 x 3 x 5 x 29

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

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

Given numbers are 142, 169, 870, 168

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

Apply this formula for all numbers.

Step1:

LCM(142, 169) = 23998

GCD(142, 169) = ( 142 x 169 ) / 23998

= 142 / 169

= 142

Step2:

LCM(1, 870) = 870

GCD(1, 870) = ( 1 x 870 ) / 870

= 1 / 870

= 1

Step3:

LCM(1, 168) = 168

GCD(1, 168) = ( 1 x 168 ) / 168

= 1 / 168

= 1

So, Greatest Common Divisor of 142, 169, 870, 168 is 1
