:1,619
Greatest Common Factor
We found the factors 220,619 . The biggest common factor number is the GCF number.
So the greatest common factor 220,619 is 1.
Lets's calculate LCM of 450,717
3 | 450, 717 |
150, 239 |
∴ So the LCM of the given numbers is 3 x 150 x 239 = 107550
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/107550
Therefore, the GCF of Fractions 220/450,619/717 is 1/107550
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 450,717 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(450,717) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(450,717) x common factors =3 x 1 = 3
LCM(450,717) = ( 450 × 717 ) / 3
LCM(450,717) = 322650 / 3
LCM(450,717) = 107550
