Greatest Common Factor
We found the factors 30,84,704 . The biggest common factor number is the GCF number.
So the greatest common factor 30,84,704 is 2.
Lets's calculate LCM of 58,42,45
2 | 58, 42, 45 |
3 | 29, 21, 45 |
29, 7, 15 |
∴ So the LCM of the given numbers is 2 x 3 x 29 x 7 x 15 = 18270
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/18270
Therefore, the GCF of Fractions 30/58,84/42,704/45 is 2/18270
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 58,42,45 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(58,42,45) = 1
common factors(in case of two or more numbers have common factors) = 6
GCF(58,42,45) x common factors =1 x 6 = 6
LCM(58,42,45) = ( 58 × 42 × 45 ) / 6
LCM(58,42,45) = 109620 / 6
LCM(58,42,45) = 18270
