The factor strings of 840 are the combinations of prime factors that multiply together to equal 840. The prime factorization of 840 is 2^3 * 3 * 5 * 7. Therefore, the factor strings of 840 are 2 * 2 * 2 * 3 * 5 * 7, 2 * 2 * 2 * 3 * 35, 2 * 2 * 2 * 15 * 7, and so on. Each factor string represents a unique combination of prime factors that multiply to give the original number, 840.
32 is not a factor of 840.
7x2x3x2x2x5=840
the longest factor string for 840 is: 2x2x2x3x5x7. I hoped that helped m! Have a good rest of your day!

The factor strings for 12 is 6*2 , 2*2*3, 4*3 if you are doing a chart than you put the length is how long the problem.
Stings with four factor that make 840
840=2*2*2*3*5*7
At least thirty-six of them.
8x3x5x7, 28x10x3 there are a ton more but don't have time to write them
2 x 420 3 x 280 4 x 210 5 x 168 6 x 140
There are a lot like 3x56x5 and there are a thousand more but i just don't want to write them all :)
32 is not a factor of 840.
2 x 2 x 2 x 3 x 5 x 7
actually 7 is a factor of 840, because when you divide 7 into 840 you get 120 with no remainders therefore making it a factor of 840.๐คก

Only one can be longest.
Only one can be longest. 2 x 2 x 2 x 3 x 5 x 7
