Greatest Common Factor
We found the factors 73,71,18,42 . The biggest common factor number is the GCF number.
So the greatest common factor 73,71,18,42 is 1.
Lets's calculate LCM of 94,75,86,90
2 | 94, 75, 86, 90 |
3 | 47, 75, 43, 45 |
5 | 47, 25, 43, 15 |
47, 5, 43, 3 |
∴ So the LCM of the given numbers is 2 x 3 x 5 x 47 x 5 x 43 x 3 = 909450
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/909450
Therefore, the GCF of Fractions 73/94,71/75,18/86,42/90 is 1/909450
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 94,75,86,90 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(94,75,86,90) = 1
common factors(in case of two or more numbers have common factors) = 60
GCF(94,75,86,90) x common factors =1 x 60 = 60
LCM(94,75,86,90) = ( 94 × 75 × 86 × 90 ) / 60
LCM(94,75,86,90) = 54567000 / 60
LCM(94,75,86,90) = 909450
