So the greatest common factor 98,54,784 is 2.
Lets's calculate LCM of 40,44,585
2 | 40, 44, 585 |
2 | 20, 22, 585 |
5 | 10, 11, 585 |
2, 11, 117 |
∴ So the LCM of the given numbers is 2 x 2 x 5 x 2 x 11 x 117 = 51480
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/51480
Therefore, the GCF of Fractions 98/40,54/44,784/585 is 2/51480
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 40,44,585 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(40,44,585) = 1
common factors(in case of two or more numbers have common factors) = 20
GCF(40,44,585) x common factors =1 x 20 = 20
LCM(40,44,585) = ( 40 × 44 × 585 ) / 20
LCM(40,44,585) = 1029600 / 20
LCM(40,44,585) = 51480
