Finding GCD of 312, 784, 643, 472 using Prime Factorization

Given Input Data is 312, 784, 643, 472

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

Prime Factorization of 312 is 2 x 2 x 2 x 3 x 13

Prime Factorization of 784 is 2 x 2 x 2 x 2 x 7 x 7

Prime Factorization of 643 is 643

Prime Factorization of 472 is 2 x 2 x 2 x 59

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

Finding GCD of 312, 784, 643, 472 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(312, 784) = 30576

GCD(312, 784) = ( 312 x 784 ) / 30576

GCD(312, 784) = 244608 / 30576

GCD(312, 784) = 8


Step2:

Here we consider the GCD from the above i.e. 8 as first number and the next as 643

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

LCM(8, 643) = 5144

GCD(8, 643) = ( 8 x 643 ) / 5144

GCD(8, 643) = 5144 / 5144

GCD(8, 643) = 1


Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 472

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

LCM(1, 472) = 472

GCD(1, 472) = ( 1 x 472 ) / 472

GCD(1, 472) = 472 / 472

GCD(1, 472) = 1

GCD of 312, 784, 643, 472 is 1
