Now, list down the factors of 351
:1,3,9,13,27,39,117,351
Greatest Common Factor
We found the factors 86,81,351 . The biggest common factor number is the GCF number.
So the greatest common factor 86,81,351 is 1.
Lets's calculate LCM of 15,506,621
3 | 15, 506, 621 |
23 | 5, 506, 207 |
5, 22, 9 |
∴ So the LCM of the given numbers is 3 x 23 x 5 x 22 x 9 = 68310
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/68310
Therefore, the GCF of Fractions 86/15,81/506,351/621 is 1/68310
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 15,506,621 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(15,506,621) = 1
common factors(in case of two or more numbers have common factors) = 69
GCF(15,506,621) x common factors =1 x 69 = 69
LCM(15,506,621) = ( 15 × 506 × 621 ) / 69
LCM(15,506,621) = 4713390 / 69
LCM(15,506,621) = 68310
