1, 19, 47, 893
Greatest Common Divisior
We found the divisors of 490, 645, 50, 893 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 490, 645, 50, 893 is 1.
Therefore, GCD of numbers 490, 645, 50, 893 is 1
Given Input Data is 490, 645, 50, 893
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 490 is 2 x 5 x 7 x 7
Prime Factorization of 645 is 3 x 5 x 43
Prime Factorization of 50 is 2 x 5 x 5
Prime Factorization of 893 is 19 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(490, 645) = 63210
GCD(490, 645) = ( 490 x 645 ) / 63210
GCD(490, 645) = 316050 / 63210
GCD(490, 645) = 5
Step2:
Here we consider the GCD from the above i.e. 5 as first number and the next as 50
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(5, 50) = 50
GCD(5, 50) = ( 5 x 50 ) / 50
GCD(5, 50) = 250 / 50
GCD(5, 50) = 5
Step3:
Here we consider the GCD from the above i.e. 5 as first number and the next as 893
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(5, 893) = 4465
GCD(5, 893) = ( 5 x 893 ) / 4465
GCD(5, 893) = 4465 / 4465
GCD(5, 893) = 1
GCD of 490, 645, 50, 893 is 1
