Greatest Common Factor

We found the factors 41,80,65,100 . The biggest common factor number is the GCF number.
So the greatest common factor 41,80,65,100 is 1.


Lets's calculate LCM of 84,87,12,18

2 84, 87, 12, 18
2 42, 87, 6, 9
3 21, 87, 3, 9
7, 29, 1, 3

∴ So the LCM of the given numbers is 2 x 2 x 3 x 7 x 29 x 1 x 3 = 7308

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/7308

Therefore, the GCF of Fractions 41/84,80/87,65/12,100/18 is 1/7308

Least Common Multiple of 84,87,12,18 with GCF Formula

Least Common Multiple of 84,87,12,18 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 84,87,12,18 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(84,87,12,18) = 3

common factors(in case of two or more numbers have common factors) = 72

GCF(84,87,12,18) x common factors =3 x 72 = 216

LCM(84,87,12,18) = ( 84 × 87 × 12 × 18 ) / 216

LCM(84,87,12,18) = 1578528 / 216

LCM(84,87,12,18) = 7308
