Make use of GCD Calculator to determine the Greatest Common Divisor of 45, 11, 90, 64 i.e. 1 largest integer that divides all the numbers equally.
GCD of 45, 11, 90, 64 is 1
GCD(45, 11, 90, 64) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 45, 11, 90, 64 is 1
GCD(45, 11, 90, 64) = 1
Given Input numbers are 45, 11, 90, 64
To find the GCD of numbers using factoring list out all the divisors of each number
Divisors of 45
List of positive integer divisors of 45 that divides 45 without a remainder.
1, 3, 5, 9, 15, 45
Divisors of 11

1, 11
Divisors of 90
List of positive integer divisors of 90 that divides 90 without a remainder.
1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, 90
Divisors of 64
List of positive integer divisors of 64 that divides 64 without a remainder.
1, 2, 4, 8, 16, 32, 64
Greatest Common Divisior
We found the divisors of 45, 11, 90, 64 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 45, 11, 90, 64 is 1.
Therefore, GCD of numbers 45, 11, 90, 64 is 1
Given Input Data is 45, 11, 90, 64
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 11 is 11
Prime Factorization of 90 is 2 x 3 x 3 x 5
Prime Factorization of 64 is 2 x 2 x 2 x 2 x 2 x 2
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, 11) = 495
GCD(45, 11) = ( 45 x 11 ) / 495
GCD(45, 11) = 495 / 495
GCD(45, 11) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 90
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 90) = 90
GCD(1, 90) = ( 1 x 90 ) / 90
GCD(1, 90) = 90 / 90
GCD(1, 90) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 64
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 64) = 64
GCD(1, 64) = ( 1 x 64 ) / 64
GCD(1, 64) = 64 / 64
GCD(1, 64) = 1
GCD of 45, 11, 90, 64 is 1
