So the greatest common factor 516,3942 is 6.
Lets's calculate LCM of 930,295
5 | 930, 295 |
186, 59 |
∴ So the LCM of the given numbers is 5 x 186 x 59 = 54870
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 6/54870
Therefore, the GCF of Fractions 516/930,3942/295 is 6/54870
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 930,295 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(930,295) = 5
common factors(in case of two or more numbers have common factors) = 1
GCF(930,295) x common factors =5 x 1 = 5
LCM(930,295) = ( 930 × 295 ) / 5
LCM(930,295) = 274350 / 5
LCM(930,295) = 54870
