Know Least Common Multiple of fractions 7809/42, 7270/820 quickly i.e. 28385715 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 7809/42, 7270/820 is 28385715.
LCM(7809/42, 7270/820) = 28385715
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 7809/42,7270/820
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 7809,7270
Least Common Multiple of Numerators i.e. LCM of 7809,7270 is 56771430.
GCF of Denominators means GCF of 42,820 as per the given fractions.
GCF of 42,820 is 2 as it is the largest common factor for these numbers.
Lets's calculate LCM of 7809,7270
Given numbers has no common factors except 1. So, there LCM is their product i.e 56771430
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 7809,7270 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(7809,7270) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(7809,7270) x common factors =1 x 1 = 1
LCM(7809,7270) = ( 7809 × 7270 ) / 1
LCM(7809,7270) = 56771430 / 1
LCM(7809,7270) = 56771430
Lets's calculate GCF of 42,820
2 | 42, 820 |
21, 410 |
∴ So the GCF of the given numbers is 2 = 2
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 56771430/2
Therefore the LCM of Fractions 7809/42,7270/820 is 28385715
