Given Input Data is 989, 129, 119, 835

Make a list of Prime Factors of all the given numbers initially

Prime Factorization of 989 is 23 x 43

Prime Factorization of 129 is 3 x 43

Prime Factorization of 119 is 7 x 17

Prime Factorization of 835 is 5 x 167

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

Step1:

Let's calculate the GCD of first two numbers

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

LCM(989, 129) = 2967

GCD(989, 129) = ( 989 x 129 ) / 2967

GCD(989, 129) = 127581 / 2967

GCD(989, 129) = 43

Step2:

Here we consider the GCD from the above i.e. 43 as first number and the next as 119

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

LCM(43, 119) = 5117

GCD(43, 119) = ( 43 x 119 ) / 5117

GCD(43, 119) = 5117 / 5117

GCD(43, 119) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 835

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

LCM(1, 835) = 835

GCD(1, 835) = ( 1 x 835 ) / 835

GCD(1, 835) = 835 / 835

GCD(1, 835) = 1

GCD of 989, 129, 119, 835 is 1
