So the greatest common factor 66,838,818 is 2.
Lets's calculate LCM of 26,40,196
2 | 26, 40, 196 |
2 | 13, 20, 98 |
13, 10, 49 |
∴ So the LCM of the given numbers is 2 x 2 x 13 x 10 x 49 = 25480
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/25480
Therefore, the GCF of Fractions 66/26,838/40,818/196 is 2/25480
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 26,40,196 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(26,40,196) = 2
common factors(in case of two or more numbers have common factors) = 4
GCF(26,40,196) x common factors =2 x 4 = 8
LCM(26,40,196) = ( 26 × 40 × 196 ) / 8
LCM(26,40,196) = 203840 / 8
LCM(26,40,196) = 25480
