:1,2,3,6,127,254,381,762
Greatest Common Factor
We found the factors 48,387,762 . The biggest common factor number is the GCF number.
So the greatest common factor 48,387,762 is 3.
Lets's calculate LCM of 55,21,210
3 | 55, 21, 210 |
5 | 55, 7, 70 |
7 | 11, 7, 14 |
11, 1, 2 |
∴ So the LCM of the given numbers is 3 x 5 x 7 x 11 x 1 x 2 = 2310
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/2310
Therefore, the GCF of Fractions 48/55,387/21,762/210 is 3/2310
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 55,21,210 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(55,21,210) = 1
common factors(in case of two or more numbers have common factors) = 105
GCF(55,21,210) x common factors =1 x 105 = 105
LCM(55,21,210) = ( 55 × 21 × 210 ) / 105
LCM(55,21,210) = 242550 / 105
LCM(55,21,210) = 2310
