So the greatest common factor 98,66,102 is 2.

Lets's calculate LCM of 40,64,30

2 40, 64, 30
2 20, 32, 15
2 10, 16, 15
5 5, 8, 15
1, 8, 3

∴ So the LCM of the given numbers is 2 x 2 x 2 x 5 x 1 x 8 x 3 = 960

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/960

Therefore, the GCF of Fractions 98/40,66/64,102/30 is 2/960

Least Common Multiple of 40,64,30 with GCF Formula

Least Common Multiple of 40,64,30 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 40,64,30 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(40,64,30) = 2

common factors(in case of two or more numbers have common factors) = 40

GCF(40,64,30) x common factors =2 x 40 = 80

LCM(40,64,30) = ( 40 × 64 × 30 ) / 80

LCM(40,64,30) = 76800 / 80

LCM(40,64,30) = 960
