Lets's calculate LCM of 42,4902
2 | 42, 4902 |
3 | 21, 2451 |
7, 817 |
∴ So the LCM of the given numbers is 2 x 3 x 7 x 817 = 34314
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/34314
Therefore, the GCF of Fractions 720/42,897/4902 is 3/34314
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 42,4902 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(42,4902) = 6
common factors(in case of two or more numbers have common factors) = 1
GCF(42,4902) x common factors =6 x 1 = 6
LCM(42,4902) = ( 42 × 4902 ) / 6
LCM(42,4902) = 205884 / 6
LCM(42,4902) = 34314
