COMMENT

Compare with A140761 A140762 A140763 A116536.

FORMULA

Find the products and sums of consecutive composites. When the products divided by the sums produce integral quotients, add terms to sequence.

EXAMPLE

a(3)=63 because 4*6*8*9*10*12*14=2903040 and 4+6+8+9+10+12+14=63; 2903040/63=46080, integral -- 63 is added to the sequence.
