1, 421
Greatest Common Divisior
We found the divisors of 641, 928, 79, 421 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 641, 928, 79, 421 is 1.
Therefore, GCD of numbers 641, 928, 79, 421 is 1
Given Input Data is 641, 928, 79, 421
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 641 is 641
Prime Factorization of 928 is 2 x 2 x 2 x 2 x 2 x 29
Prime Factorization of 79 is 79
Prime Factorization of 421 is 421
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(641, 928) = 594848
GCD(641, 928) = ( 641 x 928 ) / 594848
GCD(641, 928) = 594848 / 594848
GCD(641, 928) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 79
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 79) = 79
GCD(1, 79) = ( 1 x 79 ) / 79
GCD(1, 79) = 79 / 79
GCD(1, 79) = 1
Step3:
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
GCD of 641, 928, 79, 421 is 1
