Least Common Multiple (LCM) of 24/42, 61/68, 21/343 is 10248.
LCM(24/42, 61/68, 21/343) = 10248
LCM of 24/42, 61/68, 21/343
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 24/42,61/68,21/343
Formula to find LCM of Fractions is
LCM = LCM of Numerators/GCF of Denominators
As per the formula LCM of Fractions let’s split into two parts and find the LCM of Numerators and GCF of Denominators
In the given fractions LCM of Numerators means LCM of 24,61,21
Least Common Multiple of Numerators i.e. LCM of 24,61,21 is 10248.
GCF of Denominators means GCF of 42,68,343 as per the given fractions.
GCF of 42,68,343 is 1 as it is the largest common factor for these numbers.
Lets's calculate LCM of 24,61,21
LCM of Fractions 24/42,61/68,21/343 is 10248
| 3 | 24, 61, 21 |
| 8, 61, 7 |
∴ So the LCM of the given numbers is 3 x 8 x 61 x 7 = 10248
Least Common Multiple of 24,61,21 with GCF Formula
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 24,61,21 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(24,61,21) = 1
common factors(in case of two or more numbers have common factors) = 3
GCF(24,61,21) x common factors =1 x 3 = 3
LCM(24,61,21) = ( 24 × 61 × 21 ) / 3
LCM(24,61,21) = 30744 / 3
LCM(24,61,21) = 10248
Lets's calculate GCF of 42,68,343
∴ So GCF of numbers is 1 because of no common factors present between them.
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 10248/1
Therefore the LCM of Fractions 24/42,61/68,21/343 is 10248
