Know Least Common Multiple of fractions 619/15, 641/30, 687/87 quickly i.e. 90862391 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 619/15, 641/30, 687/87 is 90862391.
LCM(619/15, 641/30, 687/87) = 90862391
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 619/15,641/30,687/87
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 619,641,687
Least Common Multiple of Numerators i.e. LCM of 619,641,687 is 272587173.
GCF of Denominators means GCF of 15,30,87 as per the given fractions.
GCF of 15,30,87 is 3 as it is the largest common factor for these numbers.
Lets's calculate LCM of 619,641,687
Given numbers has no common factors except 1. So, there LCM is their product i.e 272587173
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 619,641,687 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(619,641,687) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(619,641,687) x common factors =1 x 1 = 1
LCM(619,641,687) = ( 619 × 641 × 687 ) / 1
LCM(619,641,687) = 272587173 / 1
LCM(619,641,687) = 272587173
Lets's calculate GCF of 15,30,87
3 | 15, 30, 87 |
5, 10, 29 |
∴ So the GCF of the given numbers is 3 = 3
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 272587173/3
Therefore the LCM of Fractions 619/15,641/30,687/87 is 90862391
