Greatest Common Divisior
We found the divisors of 15, 988, 111, 560 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 15, 988, 111, 560 is 1.
Therefore, GCD of numbers 15, 988, 111, 560 is 1
Given Input Data is 15, 988, 111, 560
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 15 is 3 x 5
Prime Factorization of 988 is 2 x 2 x 13 x 19
Prime Factorization of 111 is 3 x 37
Prime Factorization of 560 is 2 x 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(15, 988) = 14820
GCD(15, 988) = ( 15 x 988 ) / 14820
GCD(15, 988) = 14820 / 14820
GCD(15, 988) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 111
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 111) = 111
GCD(1, 111) = ( 1 x 111 ) / 111
GCD(1, 111) = 111 / 111
GCD(1, 111) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 560
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 560) = 560
GCD(1, 560) = ( 1 x 560 ) / 560
GCD(1, 560) = 560 / 560
GCD(1, 560) = 1
GCD of 15, 988, 111, 560 is 1
