So the greatest common factor 71,139,884 is 1.
Lets's calculate LCM of 90,86,881
2 | 90, 86, 881 |
45, 43, 881 |
∴ So the LCM of the given numbers is 2 x 45 x 43 x 881 = 3409470
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/3409470
Therefore, the GCF of Fractions 71/90,139/86,884/881 is 1/3409470
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 90,86,881 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(90,86,881) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(90,86,881) x common factors =1 x 2 = 2
LCM(90,86,881) = ( 90 × 86 × 881 ) / 2
LCM(90,86,881) = 6818940 / 2
LCM(90,86,881) = 3409470
