Therefore, GCD of numbers 210, 910, 71, 158 is 1

Given Input Data is 210, 910, 71, 158

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

Prime Factorization of 210 is 2 x 3 x 5 x 7

Prime Factorization of 910 is 2 x 5 x 7 x 13

Prime Factorization of 71 is 71

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(210, 910) = 2730

GCD(210, 910) = ( 210 x 910 ) / 2730

GCD(210, 910) = 191100 / 2730

GCD(210, 910) = 70

Step2:

Here we consider the GCD from the above i.e. 70 as first number and the next as 71

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

LCM(70, 71) = 4970

GCD(70, 71) = ( 70 x 71 ) / 4970

GCD(70, 71) = 4970 / 4970

GCD(70, 71) = 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 210, 910, 71, 158 is 1
