Make use of GCD Calculator to determine the Greatest Common Divisor of 440, 711, 621, 210 i.e. 1 largest integer that divides all the numbers equally.
GCD of 440, 711, 621, 210 is 1
GCD(440, 711, 621, 210) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 440, 711, 621, 210 is 1
GCD(440, 711, 621, 210) = 1
Given Input numbers are 440, 711, 621, 210
To find the GCD of numbers using factoring list out all the divisors of each number

1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210
Greatest Common Divisior
We found the divisors of 440, 711, 621, 210 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 440, 711, 621, 210 is 1.
Therefore, GCD of numbers 440, 711, 621, 210 is 1
Given Input Data is 440, 711, 621, 210
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 440 is 2 x 2 x 2 x 5 x 11
Prime Factorization of 711 is 3 x 3 x 79
Prime Factorization of 621 is 3 x 3 x 3 x 23
Prime Factorization of 210 is 2 x 3 x 5 x 7
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(440, 711) = 312840
GCD(440, 711) = ( 440 x 711 ) / 312840
GCD(440, 711) = 312840 / 312840
GCD(440, 711) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 621
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 621) = 621
GCD(1, 621) = ( 1 x 621 ) / 621
GCD(1, 621) = 621 / 621
GCD(1, 621) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 210
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 210) = 210
GCD(1, 210) = ( 1 x 210 ) / 210
GCD(1, 210) = 210 / 210
GCD(1, 210) = 1
GCD of 440, 711, 621, 210 is 1
