To find three numbers that add to 630 and can be represented using multiplication, consider the numbers 210, 210, and 210. While these three numbers add up to 630 (210 + 210 + 210 = 630), their product is (210 \times 210 \times 210). However, if you're looking for a multiplication factor, you could consider (1 \times 1 \times 630) or any variation thereof, where two of the numbers are 1 and the third is 630.
