Greatest Common Factor
We found the factors 987,417 . The biggest common factor number is the GCF number.
So the greatest common factor 987,417 is 3.
Lets's calculate LCM of 82,382
2 | 82, 382 |
41, 191 |
∴ So the LCM of the given numbers is 2 x 41 x 191 = 15662
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/15662
Therefore, the GCF of Fractions 987/82,417/382 is 3/15662
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 82,382 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(82,382) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(82,382) x common factors =2 x 1 = 2
LCM(82,382) = ( 82 × 382 ) / 2
LCM(82,382) = 31324 / 2
LCM(82,382) = 15662
