So the greatest common factor 90,49,462 is 1.
Lets's calculate LCM of 520,590,321
2 | 520, 590, 321 |
5 | 260, 295, 321 |
52, 59, 321 |
∴ So the LCM of the given numbers is 2 x 5 x 52 x 59 x 321 = 9848280
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/9848280
Therefore, the GCF of Fractions 90/520,49/590,462/321 is 1/9848280
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 520,590,321 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(520,590,321) = 1
common factors(in case of two or more numbers have common factors) = 10
GCF(520,590,321) x common factors =1 x 10 = 10
LCM(520,590,321) = ( 520 × 590 × 321 ) / 10
LCM(520,590,321) = 98482800 / 10
LCM(520,590,321) = 9848280
