Finding GCD of 247, 991, 470 using Prime Factorization

Given Input Data is 247, 991, 470

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

Prime Factorization of 247 is 13 x 19

Prime Factorization of 991 is 991

Prime Factorization of 470 is 2 x 5 x 47

Finding GCD of 247, 991, 470 using LCM Formula

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(247, 991) = 244777

GCD(247, 991) = ( 247 x 991 ) / 244777

GCD(247, 991) = 244777 / 244777

GCD(247, 991) = 1


Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 470

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

LCM(1, 470) = 470

GCD(1, 470) = ( 1 x 470 ) / 470

GCD(1, 470) = 470 / 470

GCD(1, 470) = 1

GCD of 247, 991, 470 is 1
