Given numbers are 342, 612, 787, 989

The list of prime factors of all numbers are

Prime factors of 342 are 2 x 3 x 3 x 19

Prime factors of 612 are 2 x 2 x 3 x 3 x 17

Prime factors of 787 are 787

Prime factors of 989 are 23 x 43

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

Given numbers are 342, 612, 787, 989

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

Apply this formula for all numbers.

Step1:

LCM(342, 612) = 11628

GCD(342, 612) = ( 342 x 612 ) / 11628

= 342 / 612

= 342

Step2:

LCM(18, 787) = 14166

GCD(18, 787) = ( 18 x 787 ) / 14166

= 18 / 787

= 18

Step3:

LCM(1, 989) = 989

GCD(1, 989) = ( 1 x 989 ) / 989

= 1 / 989

= 1

So, Greatest Common Divisor of 342, 612, 787, 989 is 1
