1,3,9,23,27,69,207,621
Greatest Common Factor
We found the factors 212,100,621 . The biggest common factor number is the GCF number.
So the greatest common factor 212,100,621 is 1.
Lets's calculate LCM of 95,85,984
5 | 95, 85, 984 |
19, 17, 984 |
∴ So the LCM of the given numbers is 5 x 19 x 17 x 984 = 1589160
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/1589160
Therefore, the GCF of Fractions 212/95,100/85,621/984 is 1/1589160
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 95,85,984 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(95,85,984) = 1
common factors(in case of two or more numbers have common factors) = 5
GCF(95,85,984) x common factors =1 x 5 = 5
LCM(95,85,984) = ( 95 × 85 × 984 ) / 5
LCM(95,85,984) = 7945800 / 5
LCM(95,85,984) = 1589160
