New CR advice

[Magistus71]

I want to get some advice, I am thinking of reskinning an Ape, which has a CR 1/2 by giving it an extra 2 arms, and bumping it intelligence up a little so it will basically now be a 4 armed caveman like beast. Since it now has 4 attacks instead of two what should the CR be?

According to the DMG, mathematically it would be CR 1.5625. My hunch would be round down to 1.
