So the greatest common factor 98,43,387 is 1.

Lets's calculate LCM of 72,69,36

2 72, 69, 36
2 36, 69, 18
3 9, 69, 18
3 3, 23, 6
1, 23, 2

∴ So the LCM of the given numbers is 2 x 2 x 3 x 3 x 1 x 23 x 2 = 1656

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/1656

Therefore, the GCF of Fractions 98/72,43/69,387/36 is 1/1656

Least Common Multiple of 72,69,36 with GCF Formula

Least Common Multiple of 72,69,36 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 72,69,36 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(72,69,36) = 3

common factors(in case of two or more numbers have common factors) = 36

GCF(72,69,36) x common factors =3 x 36 = 108

LCM(72,69,36) = ( 72 × 69 × 36 ) / 108

LCM(72,69,36) = 178848 / 108

LCM(72,69,36) = 1656
