Know Least Common Multiple of fractions 778/415, 7822/628 quickly i.e. 3042758 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 778/415, 7822/628 is 3042758.
LCM(778/415, 7822/628) = 3042758
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 778/415,7822/628
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 778,7822
Least Common Multiple of Numerators i.e. LCM of 778,7822 is 3042758.
GCF of Denominators means GCF of 415,628 as per the given fractions.
GCF of 415,628 is 1 as it is the largest common factor for these numbers.
Lets's calculate LCM of 778,7822
2 | 778, 7822 |
389, 3911 |
∴ So the LCM of the given numbers is 2 x 389 x 3911 = 3042758
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 778,7822 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(778,7822) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(778,7822) x common factors =2 x 1 = 2
LCM(778,7822) = ( 778 × 7822 ) / 2
LCM(778,7822) = 6085516 / 2
LCM(778,7822) = 3042758
Lets's calculate GCF of 415,628
∴ So GCF of numbers is 1 because of no common factors present between them.
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 3042758/1
Therefore the LCM of Fractions 778/415,7822/628 is 3042758
