GCD of 222, 478, 30 is 2
GCD(222, 478, 30) = 2
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 222, 478, 30 is 2
GCD(222, 478, 30) = 2
Given Input numbers are 222, 478, 30
To find the GCD of numbers using factoring list out all the divisors of each number

1, 2, 239, 478
Divisors of 30
List of positive integer divisors of 30 that divides 30 without a remainder.
1, 2, 3, 5, 6, 10, 15, 30
Greatest Common Divisior
We found the divisors of 222, 478, 30 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 222, 478, 30 is 2.
Therefore, GCD of numbers 222, 478, 30 is 2
Given Input Data is 222, 478, 30
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 222 is 2 x 3 x 37
Prime Factorization of 478 is 2 x 239
Prime Factorization of 30 is 2 x 3 x 5
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(222, 478) = 53058
GCD(222, 478) = ( 222 x 478 ) / 53058
GCD(222, 478) = 106116 / 53058
GCD(222, 478) = 2
Step2:
Here we consider the GCD from the above i.e. 2 as first number and the next as 30
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(2, 30) = 30
GCD(2, 30) = ( 2 x 30 ) / 30
GCD(2, 30) = 60 / 30
GCD(2, 30) = 2
GCD of 222, 478, 30 is 2
