Make use of GCD Calculator to determine the Greatest Common Divisor of 470, 639, 64, 634 i.e. 1 largest integer that divides all the numbers equally.
GCD of 470, 639, 64, 634 is 1
GCD(470, 639, 64, 634) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 470, 639, 64, 634 is 1
GCD(470, 639, 64, 634) = 1
Given Input numbers are 470, 639, 64, 634
To find the GCD of numbers using factoring list out all the divisors of each number

1, 2, 317, 634
Greatest Common Divisior
We found the divisors of 470, 639, 64, 634 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 470, 639, 64, 634 is 1.
Therefore, GCD of numbers 470, 639, 64, 634 is 1
Given Input Data is 470, 639, 64, 634
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 470 is 2 x 5 x 47
Prime Factorization of 639 is 3 x 3 x 71
Prime Factorization of 64 is 2 x 2 x 2 x 2 x 2 x 2
Prime Factorization of 634 is 2 x 317
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(470, 639) = 300330
GCD(470, 639) = ( 470 x 639 ) / 300330
GCD(470, 639) = 300330 / 300330
GCD(470, 639) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 64
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 64) = 64
GCD(1, 64) = ( 1 x 64 ) / 64
GCD(1, 64) = 64 / 64
GCD(1, 64) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 634
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 634) = 634
GCD(1, 634) = ( 1 x 634 ) / 634
GCD(1, 634) = 634 / 634
GCD(1, 634) = 1
GCD of 470, 639, 64, 634 is 1
