Lets's calculate LCM of 86,66,91,770

2 86, 66, 91, 770
7 43, 33, 91, 385
11 43, 33, 13, 55
43, 3, 13, 5

∴ So the LCM of the given numbers is 2 x 7 x 11 x 43 x 3 x 13 x 5 = 1291290

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/1291290

Least Common Multiple of 86,66,91,770 with GCF Formula

Least Common Multiple of 86,66,91,770 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 86,66,91,770 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(86,66,91,770) = 1

common factors(in case of two or more numbers have common factors) = 308

GCF(86,66,91,770) x common factors =1 x 308 = 308

LCM(86,66,91,770) = ( 86 × 66 × 91 × 770 ) / 308

LCM(86,66,91,770) = 397717320 / 308

LCM(86,66,91,770) = 1291290
