Greatest Common Factor
We found the factors 807,8420 . The biggest common factor number is the GCF number.
So the greatest common factor 807,8420 is 1.
Lets's calculate LCM of 210,884
| 2 | 210, 884 |
| 105, 442 |
∴ So the LCM of the given numbers is 2 x 105 x 442 = 92820
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/92820
Therefore, the GCF of Fractions 807/210,8420/884 is 1/92820
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 210,884 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(210,884) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(210,884) x common factors =2 x 1 = 2
LCM(210,884) = ( 210 × 884 ) / 2
LCM(210,884) = 185640 / 2
LCM(210,884) = 92820
