Greatest Common Divisior
We found the divisors of 820, 912, 705 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 820, 912, 705 is 1.
Therefore, GCD of numbers 820, 912, 705 is 1
Given Input Data is 820, 912, 705
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 820 is 2 x 2 x 5 x 41
Prime Factorization of 912 is 2 x 2 x 2 x 2 x 3 x 19
Prime Factorization of 705 is 3 x 5 x 47
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(820, 912) = 186960
GCD(820, 912) = ( 820 x 912 ) / 186960
GCD(820, 912) = 747840 / 186960
GCD(820, 912) = 4
Step2:
Here we consider the GCD from the above i.e. 4 as first number and the next as 705
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(4, 705) = 2820
GCD(4, 705) = ( 4 x 705 ) / 2820
GCD(4, 705) = 2820 / 2820
GCD(4, 705) = 1
GCD of 820, 912, 705 is 1
