Lets's calculate LCM of 78,98,914

LCM of Fractions 78/139,98/136,914/721 is 1746654

2 78, 98, 914
39, 49, 457

∴ So the LCM of the given numbers is 2 x 39 x 49 x 457 = 1746654

Least Common Multiple of 78,98,914 with GCF Formula

Least Common Multiple of 78,98,914 with GCF Formula

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 78,98,914 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(78,98,914) = 2

common factors(in case of two or more numbers have common factors) = 2

GCF(78,98,914) x common factors =2 x 2 = 4

LCM(78,98,914) = ( 78 × 98 × 914 ) / 4

LCM(78,98,914) = 6986616 / 4

LCM(78,98,914) = 1746654


Lets's calculate GCF of 139,136,721

∴ So GCF of numbers is 1 because of no common factors present between them.

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 1746654/1

Therefore the LCM of Fractions 78/139,98/136,914/721 is 1746654
