Know Least Common Multiple of fractions 8656/409, 4140/245 quickly i.e. 8958960 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 8656/409, 4140/245 is 8958960.
LCM(8656/409, 4140/245) = 8958960
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 8656/409,4140/245
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 8656,4140
Least Common Multiple of Numerators i.e. LCM of 8656,4140 is 8958960.
GCF of Denominators means GCF of 409,245 as per the given fractions.
GCF of 409,245 is 1 as it is the largest common factor for these numbers.
Lets's calculate LCM of 8656,4140
2 | 8656, 4140 |
2 | 4328, 2070 |
2164, 1035 |
∴ So the LCM of the given numbers is 2 x 2 x 2164 x 1035 = 8958960
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 8656,4140 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(8656,4140) = 4
common factors(in case of two or more numbers have common factors) = 1
GCF(8656,4140) x common factors =4 x 1 = 4
LCM(8656,4140) = ( 8656 × 4140 ) / 4
LCM(8656,4140) = 35835840 / 4
LCM(8656,4140) = 8958960
Lets's calculate GCF of 409,245
∴ So GCF of numbers is 1 because of no common factors present between them.
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 8958960/1
Therefore the LCM of Fractions 8656/409,4140/245 is 8958960
