So the greatest common factor 216,491 is 1.
Lets's calculate LCM of 305,570
5 | 305, 570 |
61, 114 |
∴ So the LCM of the given numbers is 5 x 61 x 114 = 34770
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/34770
Therefore, the GCF of Fractions 216/305,491/570 is 1/34770
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 305,570 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(305,570) = 5
common factors(in case of two or more numbers have common factors) = 1
GCF(305,570) x common factors =5 x 1 = 5
LCM(305,570) = ( 305 × 570 ) / 5
LCM(305,570) = 173850 / 5
LCM(305,570) = 34770
