Greatest Common Factor
We found the factors 81,93,442 . The biggest common factor number is the GCF number.
So the greatest common factor 81,93,442 is 1.
Lets's calculate LCM of 55,75,830
5 | 55, 75, 830 |
11, 15, 166 |
∴ So the LCM of the given numbers is 5 x 11 x 15 x 166 = 136950
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/136950
Therefore, the GCF of Fractions 81/55,93/75,442/830 is 1/136950
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 55,75,830 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(55,75,830) = 5
common factors(in case of two or more numbers have common factors) = 5
GCF(55,75,830) x common factors =5 x 5 = 25
LCM(55,75,830) = ( 55 × 75 × 830 ) / 25
LCM(55,75,830) = 3423750 / 25
LCM(55,75,830) = 136950
