Greatest Common Factor
We found the factors 542,685 . The biggest common factor number is the GCF number.
So the greatest common factor 542,685 is 1.
Lets's calculate LCM of 17,221
17 | 17, 221 |
1, 13 |
∴ So the LCM of the given numbers is 17 x 1 x 13 = 221
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/221
Therefore, the GCF of Fractions 542/17,685/221 is 1/221
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 17,221 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(17,221) = 17
common factors(in case of two or more numbers have common factors) = 1
GCF(17,221) x common factors =17 x 1 = 17
LCM(17,221) = ( 17 × 221 ) / 17
LCM(17,221) = 3757 / 17
LCM(17,221) = 221
