Lets's calculate LCM of 40,7992
2 | 40, 7992 |
2 | 20, 3996 |
2 | 10, 1998 |
5, 999 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 5 x 999 = 39960
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/39960
Therefore, the GCF of Fractions 748/40,838/7992 is 2/39960
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 40,7992 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(40,7992) = 8
common factors(in case of two or more numbers have common factors) = 1
GCF(40,7992) x common factors =8 x 1 = 8
LCM(40,7992) = ( 40 × 7992 ) / 8
LCM(40,7992) = 319680 / 8
LCM(40,7992) = 39960
