1, 2, 401, 802
Greatest Common Divisior
We found the divisors of 643, 139, 59, 802 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 643, 139, 59, 802 is 1.
Therefore, GCD of numbers 643, 139, 59, 802 is 1
Given Input Data is 643, 139, 59, 802
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 643 is 643
Prime Factorization of 139 is 139
Prime Factorization of 59 is 59
Prime Factorization of 802 is 2 x 401
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(643, 139) = 89377
GCD(643, 139) = ( 643 x 139 ) / 89377
GCD(643, 139) = 89377 / 89377
GCD(643, 139) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 59
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 59) = 59
GCD(1, 59) = ( 1 x 59 ) / 59
GCD(1, 59) = 59 / 59
GCD(1, 59) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 802
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 802) = 802
GCD(1, 802) = ( 1 x 802 ) / 802
GCD(1, 802) = 802 / 802
GCD(1, 802) = 1
GCD of 643, 139, 59, 802 is 1
