Greatest Common Factor
We found the factors 287,861,824 . The biggest common factor number is the GCF number.
So the greatest common factor 287,861,824 is 1.
Lets's calculate LCM of 28,30,858
2 | 28, 30, 858 |
3 | 14, 15, 429 |
14, 5, 143 |
∴ So the LCM of the given numbers is 2 x 3 x 14 x 5 x 143 = 60060
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/60060
Therefore, the GCF of Fractions 287/28,861/30,824/858 is 1/60060
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 28,30,858 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(28,30,858) = 2
common factors(in case of two or more numbers have common factors) = 6
GCF(28,30,858) x common factors =2 x 6 = 12
LCM(28,30,858) = ( 28 × 30 × 858 ) / 12
LCM(28,30,858) = 720720 / 12
LCM(28,30,858) = 60060
