Output Data In Multiples Of X?

I need the output in B1 to be in multiples of the value in A1, rounded up.

example:
Value in A1 is 6
random formula in B1: =IF(AND(N2>$AA$1,S2>0),ROUND((30/$AA$1)*AA2-Z2,0),IF(AND(N2>$AA$1,S2=""),ROUND((30/$AA$1)*AA2-Z2,0),IF(AND(N2<$AD$1,S2=""),ROUND((30/$AD$1)*AD2-Z2,0),IF(AND(N2<$AC$1,S2=""),ROUND((30/$AC$1)*AC2-Z2,0),IF(AND(N2<$AB$1,S2=""),ROUND((30/$AB$1)*AB2-Z2,0),IF(AND(N2=M2,N2<$AA$1,S2>0),ROUND(30*(AA2/N2)-Z2,0),IF(AND(N2<>M2,N2<$AA$1,S2>0),ROUND(AA2*(30/$AA$1)-Z2,0))))))))

So if the resulting value of my B1 formula is 2.33, I'd like to have the output be 6. If the resulting value is 14.55, I'd like the output to be 18.
