<p>By transitive property of equality, we can say that Tsunade and Sakura could master the sage mode, however it has been stated by Kakashi that Sakura has the least amount of chakra among the members of team 7.

I included the source from where you quoted in your message. If you quote something from an external source, you should include it as well.

Additionally, while it says Hagoromo learned sage mode from the toads, that he was able to sense natural energy before he was trained. Theoretically Hashirama could have had the same innate attunement to Senjutsu, perhaps even more so because of his natural Wood Release style being very nature-oriented.

To answer your first question,

> How did Hashirama come to know about this forest which is the home of slugs

There is no mention of how Hashirama found this place or that he learned senjutsu there. But if he did, it could be speculated that he either stumbled upon it, or he researched scrolls or other historical artifacts that led him there. Much like how Kabuto managed to find Ryūchi cave.

> what was his background to learning the Senjutsu

nothing on this was mentioned either on the manga or the anime.

> Does this mean both Tsunade and Sakura can learn the sage Jutsu?

By transitive property of equality, we can say that Tsunade and Sakura could master the sage mode, however it has been stated by Kakashi that Sakura has the least amount of chakra among the members of team 7. Also, it has been stated that a large chakra pool is required in order to amass nature energy. So that could be a handicap for Sakura. However, as her training progressed if she managed to increase her chakra pool, then theoretically she should be able to master senjutsu. The same goes for Tsunade.

Madara was shown to be able to control sage chakra, without having any training in it.
