Greatest Common Factor
We found the factors 30,99,459 . The biggest common factor number is the GCF number.
So the greatest common factor 30,99,459 is 3.
Lets's calculate LCM of 55,850,918
2 | 55, 850, 918 |
5 | 55, 425, 459 |
17 | 11, 85, 459 |
11, 5, 27 |
∴ So the LCM of the given numbers is 2 x 5 x 17 x 11 x 5 x 27 = 252450
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/252450
Therefore, the GCF of Fractions 30/55,99/850,459/918 is 3/252450
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 55,850,918 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(55,850,918) = 1
common factors(in case of two or more numbers have common factors) = 170
GCF(55,850,918) x common factors =1 x 170 = 170
LCM(55,850,918) = ( 55 × 850 × 918 ) / 170
LCM(55,850,918) = 42916500 / 170
LCM(55,850,918) = 252450
