Is there a formula that will keep my baby full longer

I'm a first time mom and my baby just turned a month old. He is getting breast milk but mostly formula. We're giving him Enfamil gentlease and he never has any stomach issues.....besides pooping about 3-5 times a day lol

But the Enfamil doesn't seem to fill him up. It's like every hour or hour in a half he's hungry again. I know it could be cluster feeding, but it seems this happens every day sometimes all day. Does it sound like I should try a different formula?
