Greatest Common Divisior
We found the divisors of 100, 998, 18, 392 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 100, 998, 18, 392 is 2.
Therefore, GCD of numbers 100, 998, 18, 392 is 2
Given Input Data is 100, 998, 18, 392
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 100 is 2 x 2 x 5 x 5
Prime Factorization of 998 is 2 x 499
Prime Factorization of 18 is 2 x 3 x 3
Prime Factorization of 392 is 2 x 2 x 2 x 7 x 7
Highest common occurrences in the given inputs are 21
Multiplying them we get the GCD as 2
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(100, 998) = 49900
GCD(100, 998) = ( 100 x 998 ) / 49900
GCD(100, 998) = 99800 / 49900
GCD(100, 998) = 2
Step2:
Here we consider the GCD from the above i.e. 2 as first number and the next as 18
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(2, 18) = 18
GCD(2, 18) = ( 2 x 18 ) / 18
GCD(2, 18) = 36 / 18
GCD(2, 18) = 2
Step3:
Here we consider the GCD from the above i.e. 2 as first number and the next as 392
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(2, 392) = 392
GCD(2, 392) = ( 2 x 392 ) / 392
GCD(2, 392) = 784 / 392
GCD(2, 392) = 2
GCD of 100, 998, 18, 392 is 2
