Lets's calculate LCM of 85,72,99
3 | 85, 72, 99 |
3 | 85, 24, 33 |
85, 8, 11 |
∴ So the LCM of the given numbers is 3 x 3 x 85 x 8 x 11 = 67320
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 14/67320
Therefore, the GCF of Fractions 546/85,798/72,280/99 is 14/67320
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 85,72,99 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(85,72,99) = 1
common factors(in case of two or more numbers have common factors) = 9
GCF(85,72,99) x common factors =1 x 9 = 9
LCM(85,72,99) = ( 85 × 72 × 99 ) / 9
LCM(85,72,99) = 605880 / 9
LCM(85,72,99) = 67320
