:1,821
Greatest Common Factor
We found the factors 665,821 . The biggest common factor number is the GCF number.
So the greatest common factor 665,821 is 1.
Lets's calculate LCM of 100,225
5 | 100, 225 |
5 | 20, 45 |
4, 9 |
∴ So the LCM of the given numbers is 5 x 5 x 4 x 9 = 900
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/900
Therefore, the GCF of Fractions 665/100,821/225 is 1/900
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 100,225 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(100,225) = 25
common factors(in case of two or more numbers have common factors) = 1
GCF(100,225) x common factors =25 x 1 = 25
LCM(100,225) = ( 100 × 225 ) / 25
LCM(100,225) = 22500 / 25
LCM(100,225) = 900
