Lets's calculate LCM of 828,176
2 | 828, 176 |
2 | 414, 88 |
207, 44 |
∴ So the LCM of the given numbers is 2 x 2 x 207 x 44 = 36432
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 77/36432
Therefore, the GCF of Fractions 308/828,385/176 is 77/36432
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 828,176 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(828,176) = 4
common factors(in case of two or more numbers have common factors) = 1
GCF(828,176) x common factors =4 x 1 = 4
LCM(828,176) = ( 828 × 176 ) / 4
LCM(828,176) = 145728 / 4
LCM(828,176) = 36432
