Lets's calculate GCF of 65,97
∴ So GCF of numbers is 1 because of no common factors present between them.
Lets's calculate LCM of 890,4590
2 | 890, 4590 |
5 | 445, 2295 |
89, 459 |
∴ So the LCM of the given numbers is 2 x 5 x 89 x 459 = 408510
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/408510
Therefore, the GCF of Fractions 65/890,97/4590 is 1/408510
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 890,4590 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(890,4590) = 10
common factors(in case of two or more numbers have common factors) = 1
GCF(890,4590) x common factors =10 x 1 = 10
LCM(890,4590) = ( 890 × 4590 ) / 10
LCM(890,4590) = 4085100 / 10
LCM(890,4590) = 408510
