Greatest Common Factor
We found the factors 43,64,45,99 . The biggest common factor number is the GCF number.
So the greatest common factor 43,64,45,99 is 1.
Lets's calculate LCM of 81,83,81,27
3 | 81, 83, 81, 27 |
3 | 27, 83, 27, 9 |
3 | 3, 83, 9, 9 |
3 | 1, 83, 3, 3 |
1, 83, 1, 1 |
∴ So the LCM of the given numbers is 3 x 3 x 3 x 3 x 1 x 83 x 1 x 1 = 6723
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/6723
Therefore, the GCF of Fractions 43/81,64/83,45/81,99/27 is 1/6723
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 81,83,81,27 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(81,83,81,27) = 1
common factors(in case of two or more numbers have common factors) = 2187
GCF(81,83,81,27) x common factors =1 x 2187 = 2187
LCM(81,83,81,27) = ( 81 × 83 × 81 × 27 ) / 2187
LCM(81,83,81,27) = 14703201 / 2187
LCM(81,83,81,27) = 6723
