1, 3, 13, 17, 39, 51, 221, 663
Greatest Common Divisior
We found the divisors of 286, 611, 15, 663 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 286, 611, 15, 663 is 1.
Therefore, GCD of numbers 286, 611, 15, 663 is 1
Given Input Data is 286, 611, 15, 663
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 286 is 2 x 11 x 13
Prime Factorization of 611 is 13 x 47
Prime Factorization of 15 is 3 x 5
Prime Factorization of 663 is 3 x 13 x 17
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(286, 611) = 13442
GCD(286, 611) = ( 286 x 611 ) / 13442
GCD(286, 611) = 174746 / 13442
GCD(286, 611) = 13
Step2:
Here we consider the GCD from the above i.e. 13 as first number and the next as 15
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(13, 15) = 195
GCD(13, 15) = ( 13 x 15 ) / 195
GCD(13, 15) = 195 / 195
GCD(13, 15) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 663
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 663) = 663
GCD(1, 663) = ( 1 x 663 ) / 663
GCD(1, 663) = 663 / 663
GCD(1, 663) = 1
GCD of 286, 611, 15, 663 is 1
