Make use of GCD Calculator to determine the Greatest Common Divisor of 220, 442, 24, 165 i.e. 1 largest integer that divides all the numbers equally.
GCD of 220, 442, 24, 165 is 1
GCD(220, 442, 24, 165) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 220, 442, 24, 165 is 1
GCD(220, 442, 24, 165) = 1
Given Input numbers are 220, 442, 24, 165
To find the GCD of numbers using factoring list out all the divisors of each number
Divisors of 220

1, 2, 3, 4, 6, 8, 12, 24
Divisors of 165
List of positive integer divisors of 165 that divides 165 without a remainder.
1, 3, 5, 11, 15, 33, 55, 165
Greatest Common Divisior
We found the divisors of 220, 442, 24, 165 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 220, 442, 24, 165 is 1.
Therefore, GCD of numbers 220, 442, 24, 165 is 1
Given Input Data is 220, 442, 24, 165
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 220 is 2 x 2 x 5 x 11
Prime Factorization of 442 is 2 x 13 x 17
Prime Factorization of 24 is 2 x 2 x 2 x 3
Prime Factorization of 165 is 3 x 5 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(220, 442) = 48620
GCD(220, 442) = ( 220 x 442 ) / 48620
GCD(220, 442) = 97240 / 48620
GCD(220, 442) = 2
Step2:
Here we consider the GCD from the above i.e. 2 as first number and the next as 24
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(2, 24) = 24
GCD(2, 24) = ( 2 x 24 ) / 24
GCD(2, 24) = 48 / 24
GCD(2, 24) = 2
Step3:
Here we consider the GCD from the above i.e. 2 as first number and the next as 165
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(2, 165) = 330
GCD(2, 165) = ( 2 x 165 ) / 330
GCD(2, 165) = 330 / 330
GCD(2, 165) = 1
GCD of 220, 442, 24, 165 is 1
