So the greatest common factor 196,940 is 4.
Lets's calculate LCM of 78,8103
3 | 78, 8103 |
26, 2701 |
∴ So the LCM of the given numbers is 3 x 26 x 2701 = 210678
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/210678
Therefore, the GCF of Fractions 196/78,940/8103 is 4/210678
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 78,8103 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(78,8103) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(78,8103) x common factors =3 x 1 = 3
LCM(78,8103) = ( 78 × 8103 ) / 3
LCM(78,8103) = 632034 / 3
LCM(78,8103) = 210678
