Finding GCD of 86, 78, 28 using Prime Factorization

Given Input Data is 86, 78, 28

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

Prime Factorization of 86 is 2 x 43

Prime Factorization of 78 is 2 x 3 x 13

Prime Factorization of 28 is 2 x 2 x 7

Finding GCD of 86, 78, 28 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(86, 78) = 3354

GCD(86, 78) = ( 86 x 78 ) / 3354

GCD(86, 78) = 6708 / 3354

GCD(86, 78) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 28

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

LCM(2, 28) = 28

GCD(2, 28) = ( 2 x 28 ) / 28

GCD(2, 28) = 56 / 28

GCD(2, 28) = 2

GCD of 86, 78, 28 is 2
