Greatest Common Factor
We found the factors 820,202,545 . The biggest common factor number is the GCF number.
So the greatest common factor 820,202,545 is 1.
Lets's calculate LCM of 42,11,286
2 | 42, 11, 286 |
11 | 21, 11, 143 |
21, 1, 13 |
∴ So the LCM of the given numbers is 2 x 11 x 21 x 1 x 13 = 6006
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/6006
Therefore, the GCF of Fractions 820/42,202/11,545/286 is 1/6006
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 42,11,286 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(42,11,286) = 1
common factors(in case of two or more numbers have common factors) = 22
GCF(42,11,286) x common factors =1 x 22 = 22
LCM(42,11,286) = ( 42 × 11 × 286 ) / 22
LCM(42,11,286) = 132132 / 22
LCM(42,11,286) = 6006
