Lets's calculate LCM of 330,774
2 | 330, 774 |
3 | 165, 387 |
55, 129 |
∴ So the LCM of the given numbers is 2 x 3 x 55 x 129 = 42570
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 55/42570
Therefore, the GCF of Fractions 385/330,275/774 is 55/42570
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 330,774 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(330,774) = 6
common factors(in case of two or more numbers have common factors) = 1
GCF(330,774) x common factors =6 x 1 = 6
LCM(330,774) = ( 330 × 774 ) / 6
LCM(330,774) = 255420 / 6
LCM(330,774) = 42570
