Given numbers are 342, 789, 868, 142

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

Apply this formula for all numbers.

Step1:

LCM(342, 789) = 89946

GCD(342, 789) = ( 342 x 789 ) / 89946

= 342 / 789

= 342

Step2:

LCM(3, 868) = 2604

GCD(3, 868) = ( 3 x 868 ) / 2604

= 3 / 868

= 3

Step3:

LCM(1, 142) = 142

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

= 1 / 142

= 1

So, Greatest Common Divisor of 342, 789, 868, 142 is 1
