Know Least Common Multiple of fractions 93/68, 42/79, 21/22, 84/698 quickly i.e. 2604 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 93/68, 42/79, 21/22, 84/698 is 2604.
LCM(93/68, 42/79, 21/22, 84/698) = 2604
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 93/68,42/79,21/22,84/698
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 93,42,21,84
Least Common Multiple of Numerators i.e. LCM of 93,42,21,84 is 2604.
GCF of Denominators means GCF of 68,79,22,698 as per the given fractions.
GCF of 68,79,22,698 is 1 as it is the largest common factor for these numbers.
Lets's calculate LCM of 93,42,21,84
2 | 93, 42, 21, 84 |
3 | 93, 21, 21, 42 |
7 | 31, 7, 7, 14 |
31, 1, 1, 2 |
∴ So the LCM of the given numbers is 2 x 3 x 7 x 31 x 1 x 1 x 2 = 2604
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 93,42,21,84 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(93,42,21,84) = 3
common factors(in case of two or more numbers have common factors) = 882
GCF(93,42,21,84) x common factors =3 x 882 = 2646
LCM(93,42,21,84) = ( 93 × 42 × 21 × 84 ) / 2646
LCM(93,42,21,84) = 6890184 / 2646
LCM(93,42,21,84) = 2604
Lets's calculate GCF of 68,79,22,698
∴ So GCF of numbers is 1 because of no common factors present between them.
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 2604/1
Therefore the LCM of Fractions 93/68,42/79,21/22,84/698 is 2604
