So the greatest common factor 800,7855 is 5.
Lets's calculate LCM of 207,987
3 | 207, 987 |
69, 329 |
∴ So the LCM of the given numbers is 3 x 69 x 329 = 68103
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/68103
Therefore, the GCF of Fractions 800/207,7855/987 is 5/68103
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 207,987 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(207,987) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(207,987) x common factors =3 x 1 = 3
LCM(207,987) = ( 207 × 987 ) / 3
LCM(207,987) = 204309 / 3
LCM(207,987) = 68103
