List of positive integer factors of 981 that divides 981 without a remainder.
1,3,9,109,327,981
Greatest Common Factor
We found the factors 742,330,981 . The biggest common factor number is the GCF number.
So the greatest common factor 742,330,981 is 1.
Lets's calculate LCM of 81,64,24
2 | 81, 64, 24 |
2 | 81, 32, 12 |
2 | 81, 16, 6 |
3 | 81, 8, 3 |
27, 8, 1 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 3 x 27 x 8 x 1 = 5184
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/5184
Therefore, the GCF of Fractions 742/81,330/64,981/24 is 1/5184
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 81,64,24 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(81,64,24) = 1
common factors(in case of two or more numbers have common factors) = 24
GCF(81,64,24) x common factors =1 x 24 = 24
LCM(81,64,24) = ( 81 × 64 × 24 ) / 24
LCM(81,64,24) = 124416 / 24
LCM(81,64,24) = 5184
