:1,2,19,23,38,46,437,874
Greatest Common Factor
We found the factors 38,72,874 . The biggest common factor number is the GCF number.
So the greatest common factor 38,72,874 is 2.
Lets's calculate LCM of 71,87,213
3 | 71, 87, 213 |
71 | 71, 29, 71 |
1, 29, 1 |
∴ So the LCM of the given numbers is 3 x 71 x 1 x 29 x 1 = 6177
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/6177
Therefore, the GCF of Fractions 38/71,72/87,874/213 is 2/6177
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 71,87,213 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(71,87,213) = 1
common factors(in case of two or more numbers have common factors) = 213
GCF(71,87,213) x common factors =1 x 213 = 213
LCM(71,87,213) = ( 71 × 87 × 213 ) / 213
LCM(71,87,213) = 1315701 / 213
LCM(71,87,213) = 6177
