We found the divisors of 98, 24, 25, 66 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 98, 24, 25, 66 is 1.

Therefore, GCD of numbers 98, 24, 25, 66 is 1

Given Input Data is 98, 24, 25, 66

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

Prime Factorization of 98 is 2 x 7 x 7

Prime Factorization of 24 is 2 x 2 x 2 x 3

Prime Factorization of 25 is 5 x 5

Prime Factorization of 66 is 2 x 3 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(98, 24) = 1176

GCD(98, 24) = ( 98 x 24 ) / 1176

GCD(98, 24) = 2352 / 1176

GCD(98, 24) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 25

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

LCM(2, 25) = 50

GCD(2, 25) = ( 2 x 25 ) / 50

GCD(2, 25) = 50 / 50

GCD(2, 25) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 66

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

LCM(1, 66) = 66

GCD(1, 66) = ( 1 x 66 ) / 66

GCD(1, 66) = 66 / 66

GCD(1, 66) = 1

GCD of 98, 24, 25, 66 is 1
