Know Least Common Multiple of fractions 1688/10, 3880/645 quickly i.e. 163736 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 1688/10, 3880/645 is 163736.
LCM(1688/10, 3880/645) = 163736
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 1688/10,3880/645
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 1688,3880
Least Common Multiple of Numerators i.e. LCM of 1688,3880 is 818680.
GCF of Denominators means GCF of 10,645 as per the given fractions.
GCF of 10,645 is 5 as it is the largest common factor for these numbers.
Lets's calculate LCM of 1688,3880
2 | 1688, 3880 |
2 | 844, 1940 |
2 | 422, 970 |
211, 485 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 211 x 485 = 818680
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 1688,3880 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(1688,3880) = 8
common factors(in case of two or more numbers have common factors) = 1
GCF(1688,3880) x common factors =8 x 1 = 8
LCM(1688,3880) = ( 1688 × 3880 ) / 8
LCM(1688,3880) = 6549440 / 8
LCM(1688,3880) = 818680
Lets's calculate GCF of 10,645
5 | 10, 645 |
2, 129 |
∴ So the GCF of the given numbers is 5 = 5
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 818680/5
Therefore the LCM of Fractions 1688/10,3880/645 is 163736
