Greatest Common Divisior
We found the divisors of 198, 974, 39, 291 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 198, 974, 39, 291 is 1.
Therefore, GCD of numbers 198, 974, 39, 291 is 1
Given Input Data is 198, 974, 39, 291
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 198 is 2 x 3 x 3 x 11
Prime Factorization of 974 is 2 x 487
Prime Factorization of 39 is 3 x 13
Prime Factorization of 291 is 3 x 97
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(198, 974) = 96426
GCD(198, 974) = ( 198 x 974 ) / 96426
GCD(198, 974) = 192852 / 96426
GCD(198, 974) = 2
Step2:
Here we consider the GCD from the above i.e. 2 as first number and the next as 39
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(2, 39) = 78
GCD(2, 39) = ( 2 x 39 ) / 78
GCD(2, 39) = 78 / 78
GCD(2, 39) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 291
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 291) = 291
GCD(1, 291) = ( 1 x 291 ) / 291
GCD(1, 291) = 291 / 291
GCD(1, 291) = 1
GCD of 198, 974, 39, 291 is 1
