Lets's calculate LCM of 806,992
2 | 806, 992 |
31 | 403, 496 |
13, 16 |
∴ So the LCM of the given numbers is 2 x 31 x 13 x 16 = 12896
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/12896
Therefore, the GCF of Fractions 265/806,420/992 is 5/12896
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 806,992 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(806,992) = 62
common factors(in case of two or more numbers have common factors) = 1
GCF(806,992) x common factors =62 x 1 = 62
LCM(806,992) = ( 806 × 992 ) / 62
LCM(806,992) = 799552 / 62
LCM(806,992) = 12896
