So the greatest common factor 388,551 is 1.
Lets's calculate LCM of 500,490
2 | 500, 490 |
5 | 250, 245 |
50, 49 |
∴ So the LCM of the given numbers is 2 x 5 x 50 x 49 = 24500
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/24500
Therefore, the GCF of Fractions 388/500,551/490 is 1/24500
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 500,490 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(500,490) = 10
common factors(in case of two or more numbers have common factors) = 1
GCF(500,490) x common factors =10 x 1 = 10
LCM(500,490) = ( 500 × 490 ) / 10
LCM(500,490) = 245000 / 10
LCM(500,490) = 24500
