Lets's calculate LCM of 780,763,818
2 | 780, 763, 818 |
390, 763, 409 |
∴ So the LCM of the given numbers is 2 x 390 x 763 x 409 = 243412260
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/243412260
Therefore, the GCF of Fractions 546/780,403/763,808/818 is 1/243412260
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 780,763,818 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(780,763,818) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(780,763,818) x common factors =1 x 2 = 2
LCM(780,763,818) = ( 780 × 763 × 818 ) / 2
LCM(780,763,818) = 486824520 / 2
LCM(780,763,818) = 243412260
