Make use of GCD Calculator to determine the Greatest Common Divisor of 28, 124, 203, 866 i.e. 1 largest integer that divides all the numbers equally.
GCD of 28, 124, 203, 866 is 1
GCD(28, 124, 203, 866) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 28, 124, 203, 866 is 1
GCD(28, 124, 203, 866) = 1
Given Input numbers are 28, 124, 203, 866
To find the GCD of numbers using factoring list out all the divisors of each number

1, 2, 433, 866
Greatest Common Divisior
We found the divisors of 28, 124, 203, 866 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 28, 124, 203, 866 is 1.
Therefore, GCD of numbers 28, 124, 203, 866 is 1
Given Input Data is 28, 124, 203, 866
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 28 is 2 x 2 x 7
Prime Factorization of 124 is 2 x 2 x 31
Prime Factorization of 203 is 7 x 29
Prime Factorization of 866 is 2 x 433
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(28, 124) = 868
GCD(28, 124) = ( 28 x 124 ) / 868
GCD(28, 124) = 3472 / 868
GCD(28, 124) = 4
Step2:
Here we consider the GCD from the above i.e. 4 as first number and the next as 203
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(4, 203) = 812
GCD(4, 203) = ( 4 x 203 ) / 812
GCD(4, 203) = 812 / 812
GCD(4, 203) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 866
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 866) = 866
GCD(1, 866) = ( 1 x 866 ) / 866
GCD(1, 866) = 866 / 866
GCD(1, 866) = 1
GCD of 28, 124, 203, 866 is 1
