So the greatest common factor 57,57,765 is 3.
Lets's calculate LCM of 709,808,909
101 | 709, 808, 909 |
709, 8, 9 |
∴ So the LCM of the given numbers is 101 x 709 x 8 x 9 = 5155848
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/5155848
Therefore, the GCF of Fractions 57/709,57/808,765/909 is 3/5155848
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 709,808,909 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(709,808,909) = 1
common factors(in case of two or more numbers have common factors) = 101
GCF(709,808,909) x common factors =1 x 101 = 101
LCM(709,808,909) = ( 709 × 808 × 909 ) / 101
LCM(709,808,909) = 520740648 / 101
LCM(709,808,909) = 5155848
