So the greatest common factor 26,17,21 is 1.

Lets's calculate LCM of 18,63,714

2 18, 63, 714
3 9, 63, 357
3 3, 21, 119
7 1, 7, 119
1, 1, 17

∴ So the LCM of the given numbers is 2 x 3 x 3 x 7 x 1 x 1 x 17 = 2142

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/2142

Therefore, the GCF of Fractions 26/18,17/63,21/714 is 1/2142

Least Common Multiple of 18,63,714 with GCF Formula

Least Common Multiple of 18,63,714 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 18,63,714 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(18,63,714) = 3

common factors(in case of two or more numbers have common factors) = 126

GCF(18,63,714) x common factors =3 x 126 = 378

LCM(18,63,714) = ( 18 × 63 × 714 ) / 378

LCM(18,63,714) = 809676 / 378

LCM(18,63,714) = 2142
