(1)
the number 42 is:
2*2*2*2*3=42
2^4*3=42
so posible factors are:
2 = 2
4 = 2*2
6 = 2*3
8 = 2*2*2
12 = 2*2*3
16 = 2*2*2*2
24 = 2*2*2*3
(2)
42*2=84
42*3=126
42*4=168
42*5=210
42*10= 420
I hope this way you understand the idea of the exceresice.
Good luck.

1.
First find the prime factorization.
42 = 6*7 = 2*3*7
Now find all combinations of 2,3 and 7.
1, 2, 3, 7, 2*3, 2*7, 3*7, 2*3*7
1, 2, 3, 7, 6, 14, 21, 42
2.
Just take 42 times 1,2,3,4, & 5:
42, 84, 126, 168, 210

On Saturday, Lamont walked 2.7 miles, or 2 and 7/10 miles. On Sunday, he walked 2 and 2/3 miles. Comparing 2 7/10 and 2 2/3, we must grub he least common deminator (LCM) which is 30. So 2 7/10 = 27/10 = 81/30 and 2 2/3 = 8/3 = 80/30 81/30 > 80/30 Lamont walked more on Saturday than Sunday. You can approach the problem through fraction work above or decimals. On Saturday = 2.7 miles Sunday = 2 2/3 miles 2 and 2/3 put into a fraction is 2.666666666666666666.... And so on Bringing us to 2.7 > 2.666666666666666.... Lamont walked more on Saturday than Sunday.

1) OK obviously 2 will divide, leaving 21, which is 3 times 7.
Those are all prime numbers, so game over.
2) Use first five numbers as multipliers:
82, 126, 164, 210, 328, etc.
