Lets's calculate LCM of 728,871
13 | 728, 871 |
56, 67 |
∴ So the LCM of the given numbers is 13 x 56 x 67 = 48776
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/48776
Therefore, the GCF of Fractions 664/728,382/871 is 2/48776
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 728,871 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(728,871) = 13
common factors(in case of two or more numbers have common factors) = 1
GCF(728,871) x common factors =13 x 1 = 13
LCM(728,871) = ( 728 × 871 ) / 13
LCM(728,871) = 634088 / 13
LCM(728,871) = 48776
