So the greatest common factor 396,288,608 is 4.
Lets's calculate LCM of 63,45,646
3 | 63, 45, 646 |
3 | 21, 15, 646 |
7, 5, 646 |
∴ So the LCM of the given numbers is 3 x 3 x 7 x 5 x 646 = 203490
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/203490
Therefore, the GCF of Fractions 396/63,288/45,608/646 is 4/203490
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 63,45,646 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(63,45,646) = 1
common factors(in case of two or more numbers have common factors) = 9
GCF(63,45,646) x common factors =1 x 9 = 9
LCM(63,45,646) = ( 63 × 45 × 646 ) / 9
LCM(63,45,646) = 1831410 / 9
LCM(63,45,646) = 203490
