Know Least Common Multiple of fractions 840/20, 296/65, 221/347 quickly i.e. 6868680 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 840/20, 296/65, 221/347 is 6868680.
LCM(840/20, 296/65, 221/347) = 6868680
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 840/20,296/65,221/347
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 840,296,221
Least Common Multiple of Numerators i.e. LCM of 840,296,221 is 6868680.
GCF of Denominators means GCF of 20,65,347 as per the given fractions.
GCF of 20,65,347 is 1 as it is the largest common factor for these numbers.
Lets's calculate LCM of 840,296,221
2 | 840, 296, 221 |
2 | 420, 148, 221 |
2 | 210, 74, 221 |
105, 37, 221 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 105 x 37 x 221 = 6868680
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 840,296,221 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(840,296,221) = 1
common factors(in case of two or more numbers have common factors) = 8
GCF(840,296,221) x common factors =1 x 8 = 8
LCM(840,296,221) = ( 840 × 296 × 221 ) / 8
LCM(840,296,221) = 54949440 / 8
LCM(840,296,221) = 6868680
Lets's calculate GCF of 20,65,347
∴ So GCF of numbers is 1 because of no common factors present between them.
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 6868680/1
Therefore the LCM of Fractions 840/20,296/65,221/347 is 6868680
