So the greatest common factor 84,45,703 is 1.

Lets's calculate LCM of 40,18,25

2 40, 18, 25
5 20, 9, 25
4, 9, 5

∴ So the LCM of the given numbers is 2 x 5 x 4 x 9 x 5 = 1800

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/1800

Therefore, the GCF of Fractions 84/40,45/18,703/25 is 1/1800

Least Common Multiple of 40,18,25 with GCF Formula

Least Common Multiple of 40,18,25 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 40,18,25 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(40,18,25) = 1

common factors(in case of two or more numbers have common factors) = 10

GCF(40,18,25) x common factors =1 x 10 = 10

LCM(40,18,25) = ( 40 × 18 × 25 ) / 10

LCM(40,18,25) = 18000 / 10

LCM(40,18,25) = 1800
