So the greatest common factor 57,657,669 is 3.
Lets's calculate LCM of 32,52,865
2 | 32, 52, 865 |
2 | 16, 26, 865 |
8, 13, 865 |
∴ So the LCM of the given numbers is 2 x 2 x 8 x 13 x 865 = 359840
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/359840
Therefore, the GCF of Fractions 57/32,657/52,669/865 is 3/359840
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 32,52,865 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(32,52,865) = 1
common factors(in case of two or more numbers have common factors) = 4
GCF(32,52,865) x common factors =1 x 4 = 4
LCM(32,52,865) = ( 32 × 52 × 865 ) / 4
LCM(32,52,865) = 1439360 / 4
LCM(32,52,865) = 359840
