Greatest Common Factor
We found the factors 68,23,94,888 . The biggest common factor number is the GCF number.
So the greatest common factor 68,23,94,888 is 1.
Lets's calculate LCM of 10,38,39,78
2 | 10, 38, 39, 78 |
3 | 5, 19, 39, 39 |
13 | 5, 19, 13, 13 |
5, 19, 1, 1 |
∴ So the LCM of the given numbers is 2 x 3 x 13 x 5 x 19 x 1 x 1 = 7410
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/7410
Therefore, the GCF of Fractions 68/10,23/38,94/39,888/78 is 1/7410
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 10,38,39,78 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(10,38,39,78) = 1
common factors(in case of two or more numbers have common factors) = 156
GCF(10,38,39,78) x common factors =1 x 156 = 156
LCM(10,38,39,78) = ( 10 × 38 × 39 × 78 ) / 156
LCM(10,38,39,78) = 1155960 / 156
LCM(10,38,39,78) = 7410
