Greatest Common Factor
We found the factors 12,29,92,66 . The biggest common factor number is the GCF number.
So the greatest common factor 12,29,92,66 is 1.
Lets's calculate LCM of 15,99,61,68
3 | 15, 99, 61, 68 |
5, 33, 61, 68 |
∴ So the LCM of the given numbers is 3 x 5 x 33 x 61 x 68 = 2053260
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/2053260
Therefore, the GCF of Fractions 12/15,29/99,92/61,66/68 is 1/2053260
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 15,99,61,68 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(15,99,61,68) = 1
common factors(in case of two or more numbers have common factors) = 3
GCF(15,99,61,68) x common factors =1 x 3 = 3
LCM(15,99,61,68) = ( 15 × 99 × 61 × 68 ) / 3
LCM(15,99,61,68) = 6159780 / 3
LCM(15,99,61,68) = 2053260
