Make use of GCD Calculator to determine the Greatest Common Divisor of 45, 311, 556, 663 i.e. 1 largest integer that divides all the numbers equally.
GCD of 45, 311, 556, 663 is 1
GCD(45, 311, 556, 663) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 45, 311, 556, 663 is 1
GCD(45, 311, 556, 663) = 1
Given Input numbers are 45, 311, 556, 663
To find the GCD of numbers using factoring list out all the divisors of each number

1, 3, 13, 17, 39, 51, 221, 663
Greatest Common Divisior
We found the divisors of 45, 311, 556, 663 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 45, 311, 556, 663 is 1.
Therefore, GCD of numbers 45, 311, 556, 663 is 1
Given Input Data is 45, 311, 556, 663
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 45 is 3 x 3 x 5
Prime Factorization of 311 is 311
Prime Factorization of 556 is 2 x 2 x 139
Prime Factorization of 663 is 3 x 13 x 17
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(45, 311) = 13995
GCD(45, 311) = ( 45 x 311 ) / 13995
GCD(45, 311) = 13995 / 13995
GCD(45, 311) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 556
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 556) = 556
GCD(1, 556) = ( 1 x 556 ) / 556
GCD(1, 556) = 556 / 556
GCD(1, 556) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 663
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 663) = 663
GCD(1, 663) = ( 1 x 663 ) / 663
GCD(1, 663) = 663 / 663
GCD(1, 663) = 1
GCD of 45, 311, 556, 663 is 1
