Lets's calculate LCM of 798,252,581
2 | 798, 252, 581 |
3 | 399, 126, 581 |
7 | 133, 42, 581 |
19, 6, 83 |
∴ So the LCM of the given numbers is 2 x 3 x 7 x 19 x 6 x 83 = 397404
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/397404
Therefore, the GCF of Fractions 256/798,117/252,513/581 is 1/397404
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 798,252,581 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(798,252,581) = 7
common factors(in case of two or more numbers have common factors) = 42
GCF(798,252,581) x common factors =7 x 42 = 294
LCM(798,252,581) = ( 798 × 252 × 581 ) / 294
LCM(798,252,581) = 116836776 / 294
LCM(798,252,581) = 397404
