Greatest Common Factor
We found the factors 422,721 . The biggest common factor number is the GCF number.
So the greatest common factor 422,721 is 1.
Lets's calculate LCM of 550,155
5 | 550, 155 |
110, 31 |
∴ So the LCM of the given numbers is 5 x 110 x 31 = 17050
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/17050
Therefore, the GCF of Fractions 422/550,721/155 is 1/17050
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 550,155 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(550,155) = 5
common factors(in case of two or more numbers have common factors) = 1
GCF(550,155) x common factors =5 x 1 = 5
LCM(550,155) = ( 550 × 155 ) / 5
LCM(550,155) = 85250 / 5
LCM(550,155) = 17050
