Greatest Common Divisior
We found the divisors of 656, 219, 236, 820 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 656, 219, 236, 820 is 1.
Therefore, GCD of numbers 656, 219, 236, 820 is 1
Given Input Data is 656, 219, 236, 820
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 656 is 2 x 2 x 2 x 2 x 41
Prime Factorization of 219 is 3 x 73
Prime Factorization of 236 is 2 x 2 x 59
Prime Factorization of 820 is 2 x 2 x 5 x 41
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(656, 219) = 143664
GCD(656, 219) = ( 656 x 219 ) / 143664
GCD(656, 219) = 143664 / 143664
GCD(656, 219) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 236
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 236) = 236
GCD(1, 236) = ( 1 x 236 ) / 236
GCD(1, 236) = 236 / 236
GCD(1, 236) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 820
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 820) = 820
GCD(1, 820) = ( 1 x 820 ) / 820
GCD(1, 820) = 820 / 820
GCD(1, 820) = 1
GCD of 656, 219, 236, 820 is 1
