Make use of GCD Calculator to determine the Greatest Common Divisor of 421, 490, 46, 906 i.e. 1 largest integer that divides all the numbers equally.
GCD of 421, 490, 46, 906 is 1
GCD(421, 490, 46, 906) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 421, 490, 46, 906 is 1
GCD(421, 490, 46, 906) = 1
Given Input numbers are 421, 490, 46, 906
To find the GCD of numbers using factoring list out all the divisors of each number

1, 2, 23, 46
Divisors of 906
List of positive integer divisors of 906 that divides 906 without a remainder.
1, 2, 3, 6, 151, 302, 453, 906
Greatest Common Divisior
We found the divisors of 421, 490, 46, 906 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 421, 490, 46, 906 is 1.
Therefore, GCD of numbers 421, 490, 46, 906 is 1
Given Input Data is 421, 490, 46, 906
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 421 is 421
Prime Factorization of 490 is 2 x 5 x 7 x 7
Prime Factorization of 46 is 2 x 23
Prime Factorization of 906 is 2 x 3 x 151
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(421, 490) = 206290
GCD(421, 490) = ( 421 x 490 ) / 206290
GCD(421, 490) = 206290 / 206290
GCD(421, 490) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 46
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 46) = 46
GCD(1, 46) = ( 1 x 46 ) / 46
GCD(1, 46) = 46 / 46
GCD(1, 46) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 906
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 906) = 906
GCD(1, 906) = ( 1 x 906 ) / 906
GCD(1, 906) = 906 / 906
GCD(1, 906) = 1
GCD of 421, 490, 46, 906 is 1
