Finding GCD of 780, 286, 745 using Prime Factorization

Given Input Data is 780, 286, 745

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

Prime Factorization of 780 is 2 x 2 x 3 x 5 x 13

Prime Factorization of 286 is 2 x 11 x 13

Prime Factorization of 745 is 5 x 149

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

Finding GCD of 780, 286, 745 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(780, 286) = 8580

GCD(780, 286) = ( 780 x 286 ) / 8580

GCD(780, 286) = 223080 / 8580

GCD(780, 286) = 26

Step2:

Here we consider the GCD from the above i.e. 26 as first number and the next as 745

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

LCM(26, 745) = 19370

GCD(26, 745) = ( 26 x 745 ) / 19370

GCD(26, 745) = 19370 / 19370

GCD(26, 745) = 1

GCD of 780, 286, 745 is 1
