Finding GCD of 985, 421, 765 using Prime Factorization

Given Input Data is 985, 421, 765

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

Prime Factorization of 985 is 5 x 197

Prime Factorization of 421 is 421

Prime Factorization of 765 is 3 x 3 x 5 x 17

Finding GCD of 985, 421, 765 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(985, 421) = 414685

GCD(985, 421) = ( 985 x 421 ) / 414685

GCD(985, 421) = 414685 / 414685

GCD(985, 421) = 1


Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 765

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

LCM(1, 765) = 765

GCD(1, 765) = ( 1 x 765 ) / 765

GCD(1, 765) = 765 / 765

GCD(1, 765) = 1

GCD of 985, 421, 765 is 1
