Greatest Common Factor
We found the factors 86,47,931 . The biggest common factor number is the GCF number.
So the greatest common factor 86,47,931 is 1.
Lets's calculate LCM of 480,902,473
2 | 480, 902, 473 |
11 | 240, 451, 473 |
240, 41, 43 |
∴ So the LCM of the given numbers is 2 x 11 x 240 x 41 x 43 = 9308640
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/9308640
Therefore, the GCF of Fractions 86/480,47/902,931/473 is 1/9308640
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 480,902,473 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(480,902,473) = 1
common factors(in case of two or more numbers have common factors) = 22
GCF(480,902,473) x common factors =1 x 22 = 22
LCM(480,902,473) = ( 480 × 902 × 473 ) / 22
LCM(480,902,473) = 204790080 / 22
LCM(480,902,473) = 9308640
