Now, list down the factors of 8
:1,2,4,8
Now, list down the factors of 61
:1,61
Now, list down the factors of 81
:1,3,9,27,81
Greatest Common Factor
We found the factors 8,61,81 . The biggest common factor number is the GCF number.
So the greatest common factor 8,61,81 is 1.
Lets's calculate LCM of 18,503,651
3 | 18, 503, 651 |
6, 503, 217 |
∴ So the LCM of the given numbers is 3 x 6 x 503 x 217 = 1964718
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/1964718
Therefore, the GCF of Fractions 8/18,61/503,81/651 is 1/1964718
The formula of LCM is LCM(a1,a2,a3....,an) = ( a1 × a2 × a3 × .... × an) / GCF(a1,a2,a3....,an) x common factors(if more than 2 numbers have common factors).
We need to calculate greatest common factor of 18,503,651 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(18,503,651) = 1
common factors(in case of two or more numbers have common factors) = 3
GCF(18,503,651) x common factors =1 x 3 = 3
LCM(18,503,651) = ( 18 × 503 × 651 ) / 3
LCM(18,503,651) = 5894154 / 3
LCM(18,503,651) = 1964718
