So the greatest common factor 872,978,850 is 2.
Lets's calculate LCM of 91,71,42
7 | 91, 71, 42 |
13, 71, 6 |
∴ So the LCM of the given numbers is 7 x 13 x 71 x 6 = 38766
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/38766
Therefore, the GCF of Fractions 872/91,978/71,850/42 is 2/38766
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 91,71,42 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(91,71,42) = 1
common factors(in case of two or more numbers have common factors) = 7
GCF(91,71,42) x common factors =1 x 7 = 7
LCM(91,71,42) = ( 91 × 71 × 42 ) / 7
LCM(91,71,42) = 271362 / 7
LCM(91,71,42) = 38766
