Finding GCD of 770, 617, 129, 393 using Prime Factorization

Given Input Data is 770, 617, 129, 393

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

Prime Factorization of 770 is 2 x 5 x 7 x 11

Prime Factorization of 617 is 617

Prime Factorization of 129 is 3 x 43

Prime Factorization of 393 is 3 x 131

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

Finding GCD of 770, 617, 129, 393 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(770, 617) = 475090

GCD(770, 617) = ( 770 x 617 ) / 475090

GCD(770, 617) = 475090 / 475090

GCD(770, 617) = 1


Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 129

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

LCM(1, 129) = 129

GCD(1, 129) = ( 1 x 129 ) / 129

GCD(1, 129) = 129 / 129

GCD(1, 129) = 1


Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 393

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

LCM(1, 393) = 393

GCD(1, 393) = ( 1 x 393 ) / 393

GCD(1, 393) = 393 / 393

GCD(1, 393) = 1

GCD of 770, 617, 129, 393 is 1
