Finding GCD of 780, 698, 777 using Prime Factorization

Given Input Data is 780, 698, 777

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 698 is 2 x 349

Prime Factorization of 777 is 3 x 7 x 37

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

Finding GCD of 780, 698, 777 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, 698) = 272220

GCD(780, 698) = ( 780 x 698 ) / 272220

GCD(780, 698) = 544440 / 272220

GCD(780, 698) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 777

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

LCM(2, 777) = 1554

GCD(2, 777) = ( 2 x 777 ) / 1554

GCD(2, 777) = 1554 / 1554

GCD(2, 777) = 1

GCD of 780, 698, 777 is 1
