:1,2,3,4,6,8,12,16,24,48
Now, list down the factors of 62
:1,2,31,62
Now, list down the factors of 81
:1,3,9,27,81
Greatest Common Factor
We found the factors 48,62,81 . The biggest common factor number is the GCF number.
So the greatest common factor 48,62,81 is 1.
Lets's calculate LCM of 63,27,990
3 | 63, 27, 990 |
3 | 21, 9, 330 |
7, 3, 110 |
∴ So the LCM of the given numbers is 3 x 3 x 7 x 3 x 110 = 20790
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/20790
Therefore, the GCF of Fractions 48/63,62/27,81/990 is 1/20790
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 63,27,990 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(63,27,990) = 9
common factors(in case of two or more numbers have common factors) = 9
GCF(63,27,990) x common factors =9 x 9 = 81
LCM(63,27,990) = ( 63 × 27 × 990 ) / 81
LCM(63,27,990) = 1683990 / 81
LCM(63,27,990) = 20790
