Factors of 3= 1 & 3
Factors of 4= 1, 2, and 4
Factors of 5= 1 & 5
Factors of 6= 1, 2, 3, and 6
Factors of 7= 1 & 7
Factors of 8= 1, 2, 4, 8
Factors of 9= 1, 3, 9

Tip: Also, a factor of any number is always 1 and itself, because you can always multiply any number by one to get the same number.
Hope I helped! :D
In probability problems, look out for the word OR and AND.
OR means adding the probability
AND means multiplying the probability
P(a) = P(jack) + P(queen) + P(king) = (4/52) + (4/52) + (4/52) = 12/52 = 3/13
P(b) = [P(9) + P(10) + P(jack)] × P(red) = [(4/52) + (4/52) + (4/52)] × (26/52)
P(b) = (12/52) × (26/52) = 3/26
P(c) = 13/52 = 1/4
P(d) = P(a diamond) + P(a heart) + P(a spade) = (13/52) + (13/52) + (13/52) = 3/4
