Make use of GCD Calculator to determine the Greatest Common Divisor of 638, 451, 76, 922 i.e. 1 largest integer that divides all the numbers equally.
GCD of 638, 451, 76, 922 is 1
GCD(638, 451, 76, 922) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 638, 451, 76, 922 is 1
GCD(638, 451, 76, 922) = 1
Given Input numbers are 638, 451, 76, 922
To find the GCD of numbers using factoring list out all the divisors of each number

1, 2, 461, 922
Greatest Common Divisior
We found the divisors of 638, 451, 76, 922 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 638, 451, 76, 922 is 1.
Therefore, GCD of numbers 638, 451, 76, 922 is 1
Given Input Data is 638, 451, 76, 922
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 638 is 2 x 11 x 29
Prime Factorization of 451 is 11 x 41
Prime Factorization of 76 is 2 x 2 x 19
Prime Factorization of 922 is 2 x 461
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(638, 451) = 26158
GCD(638, 451) = ( 638 x 451 ) / 26158
GCD(638, 451) = 287738 / 26158
GCD(638, 451) = 11
Step2:
Here we consider the GCD from the above i.e. 11 as first number and the next as 76
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(11, 76) = 836
GCD(11, 76) = ( 11 x 76 ) / 836
GCD(11, 76) = 836 / 836
GCD(11, 76) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 922
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 922) = 922
GCD(1, 922) = ( 1 x 922 ) / 922
GCD(1, 922) = 922 / 922
GCD(1, 922) = 1
GCD of 638, 451, 76, 922 is 1
