So the greatest common factor 42,673,820 is 1.
Lets's calculate LCM of 407,664,666
2 | 407, 664, 666 |
37 | 407, 332, 333 |
11, 332, 9 |
∴ So the LCM of the given numbers is 2 x 37 x 11 x 332 x 9 = 2432232
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/2432232
Therefore, the GCF of Fractions 42/407,673/664,820/666 is 1/2432232
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 407,664,666 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(407,664,666) = 1
common factors(in case of two or more numbers have common factors) = 74
GCF(407,664,666) x common factors =1 x 74 = 74
LCM(407,664,666) = ( 407 × 664 × 666 ) / 74
LCM(407,664,666) = 179985168 / 74
LCM(407,664,666) = 2432232
