Know Least Common Multiple of fractions 90/45, 683/90, 405/909 quickly i.e. 61470 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 90/45, 683/90, 405/909 is 61470.
LCM(90/45, 683/90, 405/909) = 61470
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 90/45,683/90,405/909
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 90,683,405
Least Common Multiple of Numerators i.e. LCM of 90,683,405 is 553230.
GCF of Denominators means GCF of 45,90,909 as per the given fractions.
GCF of 45,90,909 is 9 as it is the largest common factor for these numbers.
Lets's calculate LCM of 90,683,405
3 | 90, 683, 405 |
3 | 30, 683, 135 |
5 | 10, 683, 45 |
2, 683, 9 |
∴ So the LCM of the given numbers is 3 x 3 x 5 x 2 x 683 x 9 = 553230
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 90,683,405 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(90,683,405) = 1
common factors(in case of two or more numbers have common factors) = 45
GCF(90,683,405) x common factors =1 x 45 = 45
LCM(90,683,405) = ( 90 × 683 × 405 ) / 45
LCM(90,683,405) = 24895350 / 45
LCM(90,683,405) = 553230
Lets's calculate GCF of 45,90,909
3 | 45, 90, 909 |
3 | 15, 30, 303 |
5, 10, 101 |
∴ So the GCF of the given numbers is 3 x 3 = 9
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 553230/9
Therefore the LCM of Fractions 90/45,683/90,405/909 is 61470
