Greatest Common Divisior
We found the divisors of 639, 208, 913, 427 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 639, 208, 913, 427 is 1.
Therefore, GCD of numbers 639, 208, 913, 427 is 1
Given Input Data is 639, 208, 913, 427
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 208 is 2 x 2 x 2 x 2 x 13
Prime Factorization of 913 is 11 x 83
Prime Factorization of 427 is 7 x 61
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, 208) = 132912
GCD(639, 208) = ( 639 x 208 ) / 132912
GCD(639, 208) = 132912 / 132912
GCD(639, 208) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 913
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 913) = 913
GCD(1, 913) = ( 1 x 913 ) / 913
GCD(1, 913) = 913 / 913
GCD(1, 913) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 427
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 427) = 427
GCD(1, 427) = ( 1 x 427 ) / 427
GCD(1, 427) = 427 / 427
GCD(1, 427) = 1
GCD of 639, 208, 913, 427 is 1
