So the greatest common factor 18,28,11,88 is 1.

Lets's calculate LCM of 40,56,93,850

2 40, 56, 93, 850
2 20, 28, 93, 425
2 10, 14, 93, 425
5 5, 7, 93, 425
1, 7, 93, 85

∴ So the LCM of the given numbers is 2 x 2 x 2 x 5 x 1 x 7 x 93 x 85 = 2213400

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/2213400

Therefore, the GCF of Fractions 18/40,28/56,11/93,88/850 is 1/2213400

Least Common Multiple of 40,56,93,850 with GCF Formula

Least Common Multiple of 40,56,93,850 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 40,56,93,850 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(40,56,93,850) = 1

common factors(in case of two or more numbers have common factors) = 80

GCF(40,56,93,850) x common factors =1 x 80 = 80

LCM(40,56,93,850) = ( 40 × 56 × 93 × 850 ) / 80

LCM(40,56,93,850) = 177072000 / 80

LCM(40,56,93,850) = 2213400
