Make use of GCD Calculator to determine the Greatest Common Divisor of 921, 435, 32, 215 i.e. 1 largest integer that divides all the numbers equally.
GCD of 921, 435, 32, 215 is 1
GCD(921, 435, 32, 215) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 921, 435, 32, 215 is 1
GCD(921, 435, 32, 215) = 1
Given Input numbers are 921, 435, 32, 215
To find the GCD of numbers using factoring list out all the divisors of each number

1, 5, 43, 215
Greatest Common Divisior
We found the divisors of 921, 435, 32, 215 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 921, 435, 32, 215 is 1.
Therefore, GCD of numbers 921, 435, 32, 215 is 1
Given Input Data is 921, 435, 32, 215
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 921 is 3 x 307
Prime Factorization of 435 is 3 x 5 x 29
Prime Factorization of 32 is 2 x 2 x 2 x 2 x 2
Prime Factorization of 215 is 5 x 43
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(921, 435) = 133545
GCD(921, 435) = ( 921 x 435 ) / 133545
GCD(921, 435) = 400635 / 133545
GCD(921, 435) = 3
Step2:
Here we consider the GCD from the above i.e. 3 as first number and the next as 32
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(3, 32) = 96
GCD(3, 32) = ( 3 x 32 ) / 96
GCD(3, 32) = 96 / 96
GCD(3, 32) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 215
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 215) = 215
GCD(1, 215) = ( 1 x 215 ) / 215
GCD(1, 215) = 215 / 215
GCD(1, 215) = 1
GCD of 921, 435, 32, 215 is 1
