Greatest Common Factor
We found the factors 68,53,58,819 . The biggest common factor number is the GCF number.
So the greatest common factor 68,53,58,819 is 1.
Lets's calculate LCM of 78,99,63,78
2 | 78, 99, 63, 78 |
3 | 39, 99, 63, 39 |
3 | 13, 33, 21, 13 |
13 | 13, 11, 7, 13 |
1, 11, 7, 1 |
∴ So the LCM of the given numbers is 2 x 3 x 3 x 13 x 1 x 11 x 7 x 1 = 18018
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/18018
Therefore, the GCF of Fractions 68/78,53/99,58/63,819/78 is 1/18018
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 78,99,63,78 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(78,99,63,78) = 3
common factors(in case of two or more numbers have common factors) = 702
GCF(78,99,63,78) x common factors =3 x 702 = 2106
LCM(78,99,63,78) = ( 78 × 99 × 63 × 78 ) / 2106
LCM(78,99,63,78) = 37945908 / 2106
LCM(78,99,63,78) = 18018
