Make use of GCD Calculator to determine the Greatest Common Divisor of 640, 835, 91, 412 i.e. 1 largest integer that divides all the numbers equally.
GCD of 640, 835, 91, 412 is 1
GCD(640, 835, 91, 412) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 640, 835, 91, 412 is 1
GCD(640, 835, 91, 412) = 1
Given Input numbers are 640, 835, 91, 412
To find the GCD of numbers using factoring list out all the divisors of each number
Divisors of 640

1, 2, 4, 103, 206, 412
Greatest Common Divisior
We found the divisors of 640, 835, 91, 412 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 640, 835, 91, 412 is 1.
Therefore, GCD of numbers 640, 835, 91, 412 is 1
Given Input Data is 640, 835, 91, 412
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 835 is 5 x 167
Prime Factorization of 91 is 7 x 13
Prime Factorization of 412 is 2 x 2 x 103
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, 835) = 106880
GCD(640, 835) = ( 640 x 835 ) / 106880
GCD(640, 835) = 534400 / 106880
GCD(640, 835) = 5
Step2:
Here we consider the GCD from the above i.e. 5 as first number and the next as 91
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(5, 91) = 455
GCD(5, 91) = ( 5 x 91 ) / 455
GCD(5, 91) = 455 / 455
GCD(5, 91) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 412
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 412) = 412
GCD(1, 412) = ( 1 x 412 ) / 412
GCD(1, 412) = 412 / 412
GCD(1, 412) = 1
GCD of 640, 835, 91, 412 is 1
