If a girl cheated in her past relationship would she cheat again on future ones?

Met a girl a few months back at work turns out she's really into me even asking one of our coworkers for my number. I know one of my coworkers liked her however my friend tells me that there were 3 of them that liked her. Now he also told me to be careful of her because she invited one of them to go out but she ended up bringing another guy because she didn't think he would show up. What I'm trying to figure out if she was really dating multiple guys because I know some guys will talk to a girl and because she's friendly or is nice they automatically assume she likes them and they have something together. As for the other coworkers she told them that she had a boyfriend and made seemed like she wasn't into them. However the way my friend says it he said she was entertaining them and kept talking to them. I'm really into this girl however I'm not sure whether to keep trusting her or if like I said everyone just thought maybe because she's nice and friendly towards them that they thought there was something there when there really wasn't because I know some guys will do that. Also if she was cheating will she do it again. So far she hasn't done anything to make me doubt or question her but since hearing this I'm starting to second guess everything
