So the greatest common factor 87,10,99,49 is 1.

Lets's calculate LCM of 81,10,51,416

2 81, 10, 51, 416
3 81, 5, 51, 208
27, 5, 17, 208

∴ So the LCM of the given numbers is 2 x 3 x 27 x 5 x 17 x 208 = 2864160

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/2864160

Therefore, the GCF of Fractions 87/81,10/10,99/51,49/416 is 1/2864160

Least Common Multiple of 81,10,51,416 with GCF Formula

Least Common Multiple of 81,10,51,416 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 81,10,51,416 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(81,10,51,416) = 1

common factors(in case of two or more numbers have common factors) = 6

GCF(81,10,51,416) x common factors =1 x 6 = 6

LCM(81,10,51,416) = ( 81 × 10 × 51 × 416 ) / 6

LCM(81,10,51,416) = 17184960 / 6

LCM(81,10,51,416) = 2864160
