Finding GCD of 130, 643, 69 using Prime Factorization

Given Input Data is 130, 643, 69

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

Prime Factorization of 130 is 2 x 5 x 13

Prime Factorization of 643 is 643

Prime Factorization of 69 is 3 x 23

The above numbers do not have any common prime factor. So GCD is 1

Finding GCD of 130, 643, 69 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(130, 643) = 83590

GCD(130, 643) = ( 130 x 643 ) / 83590

GCD(130, 643) = 83590 / 83590

GCD(130, 643) = 1


Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 69

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

LCM(1, 69) = 69

GCD(1, 69) = ( 1 x 69 ) / 69

GCD(1, 69) = 69 / 69

GCD(1, 69) = 1

GCD of 130, 643, 69 is 1
