So the greatest common factor 72,7515 is 9.
Lets's calculate LCM of 879,3687
3 | 879, 3687 |
293, 1229 |
∴ So the LCM of the given numbers is 3 x 293 x 1229 = 1080291
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 9/1080291
Therefore, the GCF of Fractions 72/879,7515/3687 is 9/1080291
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 879,3687 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(879,3687) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(879,3687) x common factors =3 x 1 = 3
LCM(879,3687) = ( 879 × 3687 ) / 3
LCM(879,3687) = 3240873 / 3
LCM(879,3687) = 1080291
