Greatest Common Divisior
We found the divisors of 265, 842, 421, 643 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 265, 842, 421, 643 is 1.
Therefore, GCD of numbers 265, 842, 421, 643 is 1
Given Input Data is 265, 842, 421, 643
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 265 is 5 x 53
Prime Factorization of 842 is 2 x 421
Prime Factorization of 421 is 421
Prime Factorization of 643 is 643
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(265, 842) = 223130
GCD(265, 842) = ( 265 x 842 ) / 223130
GCD(265, 842) = 223130 / 223130
GCD(265, 842) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 421
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 421) = 421
GCD(1, 421) = ( 1 x 421 ) / 421
GCD(1, 421) = 421 / 421
GCD(1, 421) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 643
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 643) = 643
GCD(1, 643) = ( 1 x 643 ) / 643
GCD(1, 643) = 643 / 643
GCD(1, 643) = 1
GCD of 265, 842, 421, 643 is 1
