List the positive factors of each integer.
a. 10 b. 21 c. 24 d. 31
e. What are the possible arrangements for Example 3 if there
are 36 students singing at the concert?

Answer 1

for finding factor of 10 we need to list all +ve integers that divide 10.
by convention 1 and the number 10 itself are the factors of 10
the other factors being 2,5 bcoz 2 divides 10 as well as 5 divides 10
3 is not fator of 10 aas it does not divide 10 with 0 remainder

thus the factors of 10 are 1,2,5,10

i hope u will complete the rest
