Greatest Common Divisior
We found the divisors of 215, 628, 890, 422 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 215, 628, 890, 422 is 1.
Therefore, GCD of numbers 215, 628, 890, 422 is 1
Given Input Data is 215, 628, 890, 422
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 215 is 5 x 43
Prime Factorization of 628 is 2 x 2 x 157
Prime Factorization of 890 is 2 x 5 x 89
Prime Factorization of 422 is 2 x 211
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(215, 628) = 135020
GCD(215, 628) = ( 215 x 628 ) / 135020
GCD(215, 628) = 135020 / 135020
GCD(215, 628) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 890
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 890) = 890
GCD(1, 890) = ( 1 x 890 ) / 890
GCD(1, 890) = 890 / 890
GCD(1, 890) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 422
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 422) = 422
GCD(1, 422) = ( 1 x 422 ) / 422
GCD(1, 422) = 422 / 422
GCD(1, 422) = 1
GCD of 215, 628, 890, 422 is 1
