Planets D and G revolve around a star. Planet D
completes one orbit every 170,775 days and Planet G
completes one orbit every 9100 days. If Planets D and
G are aligned as shown in the figure, how long will it
take for them to align again?

Respuesta :

Answer:

23,905,700 days

Step-by-step explanation:

We need to find the least common multiple of 170,755 and 9100.

Write the prime factorizations:

170755 = 5×13×37×71

9100 = 2²×5²×7×13

The least common multiple is therefore:

LCM = 2²×5²×7×13×37×71

LCM = 23,905,700

Following are the calculation to the again alignment:

Given:

[tex]\bold{170,775 ,9100}[/tex]

To find:

again alignment=?

Solution:

Get the LCM of 170,775 and 9100 to find the number of days after which both planes will align together.

[tex]\to \bold{170755 = 5\times 13\times 37\times 71}\\\\ \to \bold{9100 = 2 \times 2 \times 5 \times 5 \times 7\times 13}[/tex]

Calculating the LCM:

[tex]\bold{ = 2 \times 2 \times 5\times 5\times 7\times 13\times 37\times71}\\\\ \bold{ =700 \times 13\times 37\times71}\\\\ =\bold{ 23,905,700 }\\\\[/tex]

Therefore, the Planets D and G will be aligned again after days.
