Therefore, GCD of numbers 970, 870, 89, 215 is 1

Given Input Data is 970, 870, 89, 215

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

Prime Factorization of 970 is 2 x 5 x 97

Prime Factorization of 870 is 2 x 3 x 5 x 29

Prime Factorization of 89 is 89

Prime Factorization of 215 is 5 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(970, 870) = 84390

GCD(970, 870) = ( 970 x 870 ) / 84390

GCD(970, 870) = 843900 / 84390

GCD(970, 870) = 10

Step2:

Here we consider the GCD from the above i.e. 10 as first number and the next as 89

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

LCM(10, 89) = 890

GCD(10, 89) = ( 10 x 89 ) / 890

GCD(10, 89) = 890 / 890

GCD(10, 89) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 215

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

LCM(1, 215) = 215

GCD(1, 215) = ( 1 x 215 ) / 215

GCD(1, 215) = 215 / 215

GCD(1, 215) = 1

GCD of 970, 870, 89, 215 is 1
