Lets's calculate LCM of 8122,7780

LCM of Fractions 8122/21,7780/643 is 31594580

2 8122, 7780
4061, 3890

∴ So the LCM of the given numbers is 2 x 4061 x 3890 = 31594580

Least Common Multiple of 8122,7780 with GCF Formula

Least Common Multiple of 8122,7780 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 8122,7780 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(8122,7780) = 2

common factors(in case of two or more numbers have common factors) = 1

GCF(8122,7780) x common factors =2 x 1 = 2

LCM(8122,7780) = ( 8122 × 7780 ) / 2

LCM(8122,7780) = 63189160 / 2

LCM(8122,7780) = 31594580


Lets's calculate GCF of 21,643

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

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 31594580/1

Therefore the LCM of Fractions 8122/21,7780/643 is 31594580
