To find two numbers that multiply to 420, we can start by listing the factors of 420: 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420. To find the pair of numbers, we look for a pair of factors that multiply together to give 420. One such pair is 20 and 21, as 20 * 21 = 420.
When you multiply two numbers, you get the product
there are infinites answers since answers can include decimals. Ane xample is 21*10 or 0.5*420 etc
How about: 5*84 = 420 as one example
