Finding GCD of 561, 465, 520 using Prime Factorization

Given Input Data is 561, 465, 520

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

Prime Factorization of 561 is 3 x 11 x 17

Prime Factorization of 465 is 3 x 5 x 31

Prime Factorization of 520 is 2 x 2 x 2 x 5 x 13

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

Finding GCD of 561, 465, 520 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(561, 465) = 86955

GCD(561, 465) = ( 561 x 465 ) / 86955

GCD(561, 465) = 260865 / 86955

GCD(561, 465) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 520

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

LCM(3, 520) = 1560

GCD(3, 520) = ( 3 x 520 ) / 1560

GCD(3, 520) = 1560 / 1560

GCD(3, 520) = 1

GCD of 561, 465, 520 is 1
