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.
2 x 2 x 3 x 5 x 7
I am not sure if any two consecutive numbers can add up to an even number.
Multiply to do 39 and + - to 1
420=2x2x3x5x7
To multiply two digit decimal numbers, multiply the numbers as you would without the decimals. To put the decimal in the answer, count the number of decimal places in the two numbers and put the decimal in the answer that many places to the left. For example: 5.12 x 6.35 = 32.5120. If the numbers were 51.2 x 63.5, the answer would be 3251.20.
2 and 210
2x210.
There are many possible answers. One such pair is 1 and -420.

420 = 2 x 2 x 3 x 5 x 7
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
