To find the lcm of 30,40 show work

120

Explanation:

Prime factors of 30 = 3 x 2 x 5

Prime factors of 40 = 2 x 2 x 2 x 5

All the prime factors (no repeats) time together = 2 x 2 x 2 x 5 x 3

= 120

explanation:

the universal gravitation equation. since the gravitational force is directly proportional to the mass of both interacting objects, more massive objects will attract each other with a greater gravitational force. if the mass of one of the objects is doubled, then the force of gravity between them is doubled.
