Greatest Common Divisior

We found the divisors of 67, 21, 88 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 67, 21, 88 is 1.

Therefore, GCD of numbers 67, 21, 88 is 1

Given Input Data is 67, 21, 88

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

Prime Factorization of 67 is 67

Prime Factorization of 21 is 3 x 7

Prime Factorization of 88 is 2 x 2 x 2 x 11

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

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(67, 21) = 1407

GCD(67, 21) = ( 67 x 21 ) / 1407

GCD(67, 21) = 1407 / 1407

GCD(67, 21) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 88

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

LCM(1, 88) = 88

GCD(1, 88) = ( 1 x 88 ) / 88

GCD(1, 88) = 88 / 88

GCD(1, 88) = 1

GCD of 67, 21, 88 is 1
