Finding GCD of 145, 155, 351 using Prime Factorization

Given Input Data is 145, 155, 351

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

Prime Factorization of 145 is 5 x 29

Prime Factorization of 155 is 5 x 31

Prime Factorization of 351 is 3 x 3 x 3 x 13

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

Finding GCD of 145, 155, 351 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(145, 155) = 4495

GCD(145, 155) = ( 145 x 155 ) / 4495

GCD(145, 155) = 22475 / 4495

GCD(145, 155) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 351

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

LCM(5, 351) = 1755

GCD(5, 351) = ( 5 x 351 ) / 1755

GCD(5, 351) = 1755 / 1755

GCD(5, 351) = 1

GCD of 145, 155, 351 is 1
