So the greatest common factor 704,742 is 2.
Lets's calculate LCM of 992,386
2 | 992, 386 |
496, 193 |
∴ So the LCM of the given numbers is 2 x 496 x 193 = 191456
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/191456
Therefore, the GCF of Fractions 704/992,742/386 is 2/191456
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 992,386 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(992,386) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(992,386) x common factors =2 x 1 = 2
LCM(992,386) = ( 992 × 386 ) / 2
LCM(992,386) = 382912 / 2
LCM(992,386) = 191456
