Therefore, GCD of numbers 657, 840, 350, 989 is 1

Given Input Data is 657, 840, 350, 989

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

Prime Factorization of 657 is 3 x 3 x 73

Prime Factorization of 840 is 2 x 2 x 2 x 3 x 5 x 7

Prime Factorization of 350 is 2 x 5 x 5 x 7

Prime Factorization of 989 is 23 x 43

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(657, 840) = 183960

GCD(657, 840) = ( 657 x 840 ) / 183960

GCD(657, 840) = 551880 / 183960

GCD(657, 840) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 350

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

LCM(3, 350) = 1050

GCD(3, 350) = ( 3 x 350 ) / 1050

GCD(3, 350) = 1050 / 1050

GCD(3, 350) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 989

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

LCM(1, 989) = 989

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

GCD(1, 989) = 989 / 989

GCD(1, 989) = 1

GCD of 657, 840, 350, 989 is 1
