Therefore, GCD of numbers 870, 207, 274 is 1

Given Input Data is 870, 207, 274

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

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

Prime Factorization of 207 is 3 x 3 x 23

Prime Factorization of 274 is 2 x 137

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(870, 207) = 60030

GCD(870, 207) = ( 870 x 207 ) / 60030

GCD(870, 207) = 180090 / 60030

GCD(870, 207) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 274

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

LCM(3, 274) = 822

GCD(3, 274) = ( 3 x 274 ) / 822

GCD(3, 274) = 822 / 822

GCD(3, 274) = 1

GCD of 870, 207, 274 is 1
