Know Least Common Multiple of fractions 187/81, 372/14, 252/642 quickly i.e. 1460844 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 187/81, 372/14, 252/642 is 1460844.
LCM(187/81, 372/14, 252/642) = 1460844
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 187/81,372/14,252/642
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 187,372,252
Least Common Multiple of Numerators i.e. LCM of 187,372,252 is 1460844.
GCF of Denominators means GCF of 81,14,642 as per the given fractions.
GCF of 81,14,642 is 1 as it is the largest common factor for these numbers.
Lets's calculate LCM of 187,372,252
2 | 187, 372, 252 |
2 | 187, 186, 126 |
3 | 187, 93, 63 |
187, 31, 21 |
∴ So the LCM of the given numbers is 2 x 2 x 3 x 187 x 31 x 21 = 1460844
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 187,372,252 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(187,372,252) = 1
common factors(in case of two or more numbers have common factors) = 12
GCF(187,372,252) x common factors =1 x 12 = 12
LCM(187,372,252) = ( 187 × 372 × 252 ) / 12
LCM(187,372,252) = 17530128 / 12
LCM(187,372,252) = 1460844
Lets's calculate GCF of 81,14,642
∴ So GCF of numbers is 1 because of no common factors present between them.
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 1460844/1
Therefore the LCM of Fractions 187/81,372/14,252/642 is 1460844
