Greatest Common Divisior
We found the divisors of 647, 619, 602, 511 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 647, 619, 602, 511 is 1.
Therefore, GCD of numbers 647, 619, 602, 511 is 1
Given Input Data is 647, 619, 602, 511
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 647 is 647
Prime Factorization of 619 is 619
Prime Factorization of 602 is 2 x 7 x 43
Prime Factorization of 511 is 7 x 73
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(647, 619) = 400493
GCD(647, 619) = ( 647 x 619 ) / 400493
GCD(647, 619) = 400493 / 400493
GCD(647, 619) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 602
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 602) = 602
GCD(1, 602) = ( 1 x 602 ) / 602
GCD(1, 602) = 602 / 602
GCD(1, 602) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 511
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 511) = 511
GCD(1, 511) = ( 1 x 511 ) / 511
GCD(1, 511) = 511 / 511
GCD(1, 511) = 1
GCD of 647, 619, 602, 511 is 1
