Therefore, GCD of numbers 215, 235, 220 is 5

Given Input Data is 215, 235, 220

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

Prime Factorization of 215 is 5 x 43

Prime Factorization of 235 is 5 x 47

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

Highest common occurrences in the given inputs are 5¹

Multiplying them we get the GCD as 5

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(215, 235) = 10105

GCD(215, 235) = ( 215 x 235 ) / 10105

GCD(215, 235) = 50525 / 10105

GCD(215, 235) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 220

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

LCM(5, 220) = 220

GCD(5, 220) = ( 5 x 220 ) / 220

GCD(5, 220) = 1100 / 220

GCD(5, 220) = 5

GCD of 215, 235, 220 is 5
