So the greatest common factor 768,533 is 1.
Lets's calculate LCM of 490,254
2 | 490, 254 |
245, 127 |
∴ So the LCM of the given numbers is 2 x 245 x 127 = 62230
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/62230
Therefore, the GCF of Fractions 768/490,533/254 is 1/62230
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 490,254 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(490,254) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(490,254) x common factors =2 x 1 = 2
LCM(490,254) = ( 490 × 254 ) / 2
LCM(490,254) = 124460 / 2
LCM(490,254) = 62230
