Greatest Common Divisior
We found the divisors of 639, 305, 766, 483 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 639, 305, 766, 483 is 1.
Therefore, GCD of numbers 639, 305, 766, 483 is 1
Given Input Data is 639, 305, 766, 483
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 639 is 3 x 3 x 71
Prime Factorization of 305 is 5 x 61
Prime Factorization of 766 is 2 x 383
Prime Factorization of 483 is 3 x 7 x 23
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(639, 305) = 194895
GCD(639, 305) = ( 639 x 305 ) / 194895
GCD(639, 305) = 194895 / 194895
GCD(639, 305) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 766
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 766) = 766
GCD(1, 766) = ( 1 x 766 ) / 766
GCD(1, 766) = 766 / 766
GCD(1, 766) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 483
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 483) = 483
GCD(1, 483) = ( 1 x 483 ) / 483
GCD(1, 483) = 483 / 483
GCD(1, 483) = 1
GCD of 639, 305, 766, 483 is 1
