Make use of GCD Calculator to determine the Greatest Common Divisor of 630, 222, 205, 280 i.e. 1 largest integer that divides all the numbers equally.
GCD of 630, 222, 205, 280 is 1
GCD(630, 222, 205, 280) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 630, 222, 205, 280 is 1
GCD(630, 222, 205, 280) = 1
Given Input numbers are 630, 222, 205, 280
To find the GCD of numbers using factoring list out all the divisors of each number

1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280
Greatest Common Divisior
We found the divisors of 630, 222, 205, 280 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 630, 222, 205, 280 is 1.
Therefore, GCD of numbers 630, 222, 205, 280 is 1
Given Input Data is 630, 222, 205, 280
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 630 is 2 x 3 x 3 x 5 x 7
Prime Factorization of 222 is 2 x 3 x 37
Prime Factorization of 205 is 5 x 41
Prime Factorization of 280 is 2 x 2 x 2 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(630, 222) = 23310
GCD(630, 222) = ( 630 x 222 ) / 23310
GCD(630, 222) = 139860 / 23310
GCD(630, 222) = 6
Step2:
Here we consider the GCD from the above i.e. 6 as first number and the next as 205
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(6, 205) = 1230
GCD(6, 205) = ( 6 x 205 ) / 1230
GCD(6, 205) = 1230 / 1230
GCD(6, 205) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 280
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 280) = 280
GCD(1, 280) = ( 1 x 280 ) / 280
GCD(1, 280) = 280 / 280
GCD(1, 280) = 1
GCD of 630, 222, 205, 280 is 1
