Lets's calculate LCM of 36,30,40

2 36, 30, 40
2 18, 15, 20
3 9, 15, 10
5 3, 5, 10
3, 1, 2

∴ So the LCM of the given numbers is 2 x 2 x 3 x 5 x 3 x 1 x 2 = 360

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/360

Therefore, the GCF of Fractions 71/36,98/30,863/40 is 1/360

Least Common Multiple of 36,30,40 with GCF Formula

Least Common Multiple of 36,30,40 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 36,30,40 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(36,30,40) = 2

common factors(in case of two or more numbers have common factors) = 60

GCF(36,30,40) x common factors =2 x 60 = 120

LCM(36,30,40) = ( 36 × 30 × 40 ) / 120

LCM(36,30,40) = 43200 / 120

LCM(36,30,40) = 360
