Greatest Common Divisior
We found the divisors of 845, 408, 707, 406 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 845, 408, 707, 406 is 1.
Therefore, GCD of numbers 845, 408, 707, 406 is 1
Given Input Data is 845, 408, 707, 406
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 845 is 5 x 13 x 13
Prime Factorization of 408 is 2 x 2 x 2 x 3 x 17
Prime Factorization of 707 is 7 x 101
Prime Factorization of 406 is 2 x 7 x 29
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(845, 408) = 344760
GCD(845, 408) = ( 845 x 408 ) / 344760
GCD(845, 408) = 344760 / 344760
GCD(845, 408) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 707
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 707) = 707
GCD(1, 707) = ( 1 x 707 ) / 707
GCD(1, 707) = 707 / 707
GCD(1, 707) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 406
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 406) = 406
GCD(1, 406) = ( 1 x 406 ) / 406
GCD(1, 406) = 406 / 406
GCD(1, 406) = 1
GCD of 845, 408, 707, 406 is 1
