Know Least Common Multiple of fractions 406/688, 2800/3608 quickly i.e. 10150 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 406/688, 2800/3608 is 10150.
LCM(406/688, 2800/3608) = 10150
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 406/688,2800/3608
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 406,2800
Least Common Multiple of Numerators i.e. LCM of 406,2800 is 81200.
GCF of Denominators means GCF of 688,3608 as per the given fractions.
GCF of 688,3608 is 8 as it is the largest common factor for these numbers.
Lets's calculate LCM of 406,2800
2 | 406, 2800 |
7 | 203, 1400 |
29, 200 |
∴ So the LCM of the given numbers is 2 x 7 x 29 x 200 = 81200
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 406,2800 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(406,2800) = 14
common factors(in case of two or more numbers have common factors) = 1
GCF(406,2800) x common factors =14 x 1 = 14
LCM(406,2800) = ( 406 × 2800 ) / 14
LCM(406,2800) = 1136800 / 14
LCM(406,2800) = 81200
Lets's calculate GCF of 688,3608
2 | 688, 3608 |
2 | 344, 1804 |
2 | 172, 902 |
86, 451 |
∴ So the GCF of the given numbers is 2 x 2 x 2 = 8
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 81200/8
Therefore the LCM of Fractions 406/688,2800/3608 is 10150
