Finding GCD of 959, 121, 505, 643 using Prime Factorization

Given Input Data is 959, 121, 505, 643

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

Prime Factorization of 959 is 7 x 137

Prime Factorization of 121 is 11 x 11

Prime Factorization of 505 is 5 x 101

Prime Factorization of 643 is 643

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

Finding GCD of 959, 121, 505, 643 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(959, 121) = 116039

GCD(959, 121) = ( 959 x 121 ) / 116039

GCD(959, 121) = 116039 / 116039

GCD(959, 121) = 1


Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 505

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

LCM(1, 505) = 505

GCD(1, 505) = ( 1 x 505 ) / 505

GCD(1, 505) = 505 / 505

GCD(1, 505) = 1


Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 643

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

LCM(1, 643) = 643

GCD(1, 643) = ( 1 x 643 ) / 643

GCD(1, 643) = 643 / 643

GCD(1, 643) = 1

GCD of 959, 121, 505, 643 is 1
