Finding GCD of 657, 180, 785, 392 using Prime Factorization

Given Input Data is 657, 180, 785, 392

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

Prime Factorization of 657 is 3 x 3 x 73

Prime Factorization of 180 is 2 x 2 x 3 x 3 x 5

Prime Factorization of 785 is 5 x 157

Prime Factorization of 392 is 2 x 2 x 2 x 7 x 7

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

Finding GCD of 657, 180, 785, 392 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(657, 180) = 13140

GCD(657, 180) = ( 657 x 180 ) / 13140

GCD(657, 180) = 118260 / 13140

GCD(657, 180) = 9


Step2:

Here we consider the GCD from the above i.e. 9 as first number and the next as 785

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

LCM(9, 785) = 7065

GCD(9, 785) = ( 9 x 785 ) / 7065

GCD(9, 785) = 7065 / 7065

GCD(9, 785) = 1


Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 392

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

LCM(1, 392) = 392

GCD(1, 392) = ( 1 x 392 ) / 392

GCD(1, 392) = 392 / 392

GCD(1, 392) = 1

GCD of 657, 180, 785, 392 is 1
