Know Least Common Multiple of fractions 85/638, 88/781, 392/683 quickly i.e. 366520 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 85/638, 88/781, 392/683 is 366520.
LCM(85/638, 88/781, 392/683) = 366520
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 85/638,88/781,392/683
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 85,88,392
Least Common Multiple of Numerators i.e. LCM of 85,88,392 is 366520.
GCF of Denominators means GCF of 638,781,683 as per the given fractions.
GCF of 638,781,683 is 1 as it is the largest common factor for these numbers.
Lets's calculate LCM of 85,88,392
2 | 85, 88, 392 |
2 | 85, 44, 196 |
2 | 85, 22, 98 |
85, 11, 49 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 85 x 11 x 49 = 366520
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 85,88,392 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(85,88,392) = 1
common factors(in case of two or more numbers have common factors) = 8
GCF(85,88,392) x common factors =1 x 8 = 8
LCM(85,88,392) = ( 85 × 88 × 392 ) / 8
LCM(85,88,392) = 2932160 / 8
LCM(85,88,392) = 366520
Lets's calculate GCF of 638,781,683
∴ So GCF of numbers is 1 because of no common factors present between them.
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 366520/1
Therefore the LCM of Fractions 85/638,88/781,392/683 is 366520
