1, 487
Greatest Common Divisior
We found the divisors of 640, 756, 465, 487 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 640, 756, 465, 487 is 1.
Therefore, GCD of numbers 640, 756, 465, 487 is 1
Given Input Data is 640, 756, 465, 487
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 640 is 2 x 2 x 2 x 2 x 2 x 2 x 2 x 5
Prime Factorization of 756 is 2 x 2 x 3 x 3 x 3 x 7
Prime Factorization of 465 is 3 x 5 x 31
Prime Factorization of 487 is 487
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(640, 756) = 120960
GCD(640, 756) = ( 640 x 756 ) / 120960
GCD(640, 756) = 483840 / 120960
GCD(640, 756) = 4
Step2:
Here we consider the GCD from the above i.e. 4 as first number and the next as 465
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(4, 465) = 1860
GCD(4, 465) = ( 4 x 465 ) / 1860
GCD(4, 465) = 1860 / 1860
GCD(4, 465) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 487
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 487) = 487
GCD(1, 487) = ( 1 x 487 ) / 487
GCD(1, 487) = 487 / 487
GCD(1, 487) = 1
GCD of 640, 756, 465, 487 is 1
