Lets's calculate LCM of 57,25,800
| 5 | 57, 25, 800 |
| 5 | 57, 5, 160 |
| 57, 1, 32 |
∴ So the LCM of the given numbers is 5 x 5 x 57 x 1 x 32 = 45600
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/45600
Therefore, the GCF of Fractions 42/57,41/25,46/800 is 1/45600
Least Common Multiple of 57,25,800 with GCF Formula
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 57,25,800 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(57,25,800) = 1
common factors(in case of two or more numbers have common factors) = 25
GCF(57,25,800) x common factors =1 x 25 = 25
LCM(57,25,800) = ( 57 × 25 × 800 ) / 25
LCM(57,25,800) = 1140000 / 25
LCM(57,25,800) = 45600
