Therefore, GCD of numbers 35, 693, 989, 158 is 1

Given Input Data is 35, 693, 989, 158

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

Prime Factorization of 35 is 5 x 7

Prime Factorization of 693 is 3 x 3 x 7 x 11

Prime Factorization of 989 is 23 x 43

Prime Factorization of 158 is 2 x 79

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(35, 693) = 3465

GCD(35, 693) = ( 35 x 693 ) / 3465

GCD(35, 693) = 24255 / 3465

GCD(35, 693) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 989

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

LCM(7, 989) = 6923

GCD(7, 989) = ( 7 x 989 ) / 6923

GCD(7, 989) = 6923 / 6923

GCD(7, 989) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 158

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

LCM(1, 158) = 158

GCD(1, 158) = ( 1 x 158 ) / 158

GCD(1, 158) = 158 / 158

GCD(1, 158) = 1

GCD of 35, 693, 989, 158 is 1
