Make use of GCD Calculator to determine the Greatest Common Divisor of 512, 640, 64, 905 i.e. 1 largest integer that divides all the numbers equally.
GCD of 512, 640, 64, 905 is 1
GCD(512, 640, 64, 905) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 512, 640, 64, 905 is 1
GCD(512, 640, 64, 905) = 1
Given Input numbers are 512, 640, 64, 905
To find the GCD of numbers using factoring list out all the divisors of each number

1, 5, 181, 905
Greatest Common Divisior
We found the divisors of 512, 640, 64, 905 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 512, 640, 64, 905 is 1.
Therefore, GCD of numbers 512, 640, 64, 905 is 1
Given Input Data is 512, 640, 64, 905
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 512 is 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2
Prime Factorization of 640 is 2 x 2 x 2 x 2 x 2 x 2 x 2 x 5
Prime Factorization of 64 is 2 x 2 x 2 x 2 x 2 x 2
Prime Factorization of 905 is 5 x 181
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(512, 640) = 2560
GCD(512, 640) = ( 512 x 640 ) / 2560
GCD(512, 640) = 327680 / 2560
GCD(512, 640) = 128
Step2:
Here we consider the GCD from the above i.e. 128 as first number and the next as 64
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(128, 64) = 128
GCD(128, 64) = ( 128 x 64 ) / 128
GCD(128, 64) = 8192 / 128
GCD(128, 64) = 64
Step3:
Here we consider the GCD from the above i.e. 64 as first number and the next as 905
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(64, 905) = 57920
GCD(64, 905) = ( 64 x 905 ) / 57920
GCD(64, 905) = 57920 / 57920
GCD(64, 905) = 1
GCD of 512, 640, 64, 905 is 1
