1, 659
Greatest Common Divisior
We found the divisors of 647, 520, 57, 659 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 647, 520, 57, 659 is 1.
Therefore, GCD of numbers 647, 520, 57, 659 is 1
Given Input Data is 647, 520, 57, 659
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 647 is 647
Prime Factorization of 520 is 2 x 2 x 2 x 5 x 13
Prime Factorization of 57 is 3 x 19
Prime Factorization of 659 is 659
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, 520) = 336440
GCD(647, 520) = ( 647 x 520 ) / 336440
GCD(647, 520) = 336440 / 336440
GCD(647, 520) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 57
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 57) = 57
GCD(1, 57) = ( 1 x 57 ) / 57
GCD(1, 57) = 57 / 57
GCD(1, 57) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 659
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 659) = 659
GCD(1, 659) = ( 1 x 659 ) / 659
GCD(1, 659) = 659 / 659
GCD(1, 659) = 1
GCD of 647, 520, 57, 659 is 1
