Lets's calculate LCM of 76,5780
2 | 76, 5780 |
2 | 38, 2890 |
19, 1445 |
∴ So the LCM of the given numbers is 2 x 2 x 19 x 1445 = 109820
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/109820
Therefore, the GCF of Fractions 831/76,742/5780 is 1/109820
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 76,5780 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(76,5780) = 4
common factors(in case of two or more numbers have common factors) = 1
GCF(76,5780) x common factors =4 x 1 = 4
LCM(76,5780) = ( 76 × 5780 ) / 4
LCM(76,5780) = 439280 / 4
LCM(76,5780) = 109820
