So the greatest common factor 56,21,93,85 is 1.

Lets's calculate LCM of 87,40,43,48

2 87, 40, 43, 48
2 87, 20, 43, 24
2 87, 10, 43, 12
3 87, 5, 43, 6
29, 5, 43, 2

∴ So the LCM of the given numbers is 2 x 2 x 2 x 3 x 29 x 5 x 43 x 2 = 299280

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/299280

Therefore, the GCF of Fractions 56/87,21/40,93/43,85/48 is 1/299280

Least Common Multiple of 87,40,43,48 with GCF Formula

Least Common Multiple of 87,40,43,48 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 87,40,43,48 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(87,40,43,48) = 1

common factors(in case of two or more numbers have common factors) = 24

GCF(87,40,43,48) x common factors =1 x 24 = 24

LCM(87,40,43,48) = ( 87 × 40 × 43 × 48 ) / 24

LCM(87,40,43,48) = 7182720 / 24

LCM(87,40,43,48) = 299280
