We found the divisors of 69, 66, 98 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 69, 66, 98 is 1.

Therefore, GCD of numbers 69, 66, 98 is 1

Given Input Data is 69, 66, 98

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

Prime Factorization of 69 is 3 x 23

Prime Factorization of 66 is 2 x 3 x 11

Prime Factorization of 98 is 2 x 7 x 7

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(69, 66) = 1518

GCD(69, 66) = ( 69 x 66 ) / 1518

GCD(69, 66) = 4554 / 1518

GCD(69, 66) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 98

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

LCM(3, 98) = 294

GCD(3, 98) = ( 3 x 98 ) / 294

GCD(3, 98) = 294 / 294

GCD(3, 98) = 1

GCD of 69, 66, 98 is 1
