Therefore, GCD of numbers 220, 268, 168 is 4

Given Input Data is 220, 268, 168

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

Prime Factorization of 220 is 2 x 2 x 5 x 11

Prime Factorization of 268 is 2 x 2 x 67

Prime Factorization of 168 is 2 x 2 x 2 x 3 x 7

Highest common occurrences in the given inputs are 2²

Multiplying them we get the GCD as 4

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(220, 268) = 14740

GCD(220, 268) = ( 220 x 268 ) / 14740

GCD(220, 268) = 58960 / 14740

GCD(220, 268) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 168

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

LCM(4, 168) = 168

GCD(4, 168) = ( 4 x 168 ) / 168

GCD(4, 168) = 672 / 168

GCD(4, 168) = 4

GCD of 220, 268, 168 is 4
