So the greatest common factor 86,285,940 is 1.
Lets's calculate LCM of 39,20,444
2 | 39, 20, 444 |
2 | 39, 10, 222 |
3 | 39, 5, 111 |
13, 5, 37 |
∴ So the LCM of the given numbers is 2 x 2 x 3 x 13 x 5 x 37 = 28860
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/28860
Therefore, the GCF of Fractions 86/39,285/20,940/444 is 1/28860
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 39,20,444 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(39,20,444) = 1
common factors(in case of two or more numbers have common factors) = 12
GCF(39,20,444) x common factors =1 x 12 = 12
LCM(39,20,444) = ( 39 × 20 × 444 ) / 12
LCM(39,20,444) = 346320 / 12
LCM(39,20,444) = 28860
