Lets's calculate LCM of 66,15,847

3 66, 15, 847
11 22, 5, 847
2, 5, 77

∴ So the LCM of the given numbers is 3 x 11 x 2 x 5 x 77 = 25410

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/25410

Therefore, the GCF of Fractions 81/66,35/15,286/847 is 1/25410

Least Common Multiple of 66,15,847 with GCF Formula

Least Common Multiple of 66,15,847 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 66,15,847 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(66,15,847) = 1

common factors(in case of two or more numbers have common factors) = 33

GCF(66,15,847) x common factors =1 x 33 = 33

LCM(66,15,847) = ( 66 × 15 × 847 ) / 33

LCM(66,15,847) = 838530 / 33

LCM(66,15,847) = 25410
