Greatest Common Divisior

We found the divisors of 62, 66, 81 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 62, 66, 81 is 1.

Therefore, GCD of numbers 62, 66, 81 is 1

Given Input Data is 62, 66, 81

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

Prime Factorization of 62 is 2 x 31

Prime Factorization of 66 is 2 x 3 x 11

Prime Factorization of 81 is 3 x 3 x 3 x 3

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(62, 66) = 2046

GCD(62, 66) = ( 62 x 66 ) / 2046

GCD(62, 66) = 4092 / 2046

GCD(62, 66) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 81

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

LCM(2, 81) = 162

GCD(2, 81) = ( 2 x 81 ) / 162

GCD(2, 81) = 162 / 162

GCD(2, 81) = 1

GCD of 62, 66, 81 is 1
