Which of the following numbers is a factor of `A`?

`\large{`

`WRONGFACTORS_SORTED.join( "," )`}

`B`

`wrong`

By definition, a factor of a number will divide evenly into that number. We can start by dividing

by each of our answer choices.`A`

`A` \div `WRONG` = `floor( A / WRONG )`\text{ R }`( A % WRONG )`

The only answer choice that divides into

with no remainder is `A`

. `B``\quad`

* `FACTOR`

= `B`

.`A`

We can check our answer by looking at the prime factorization of both numbers. Notice that the prime factors of

are contained within the prime factors of `B`

.`A`

`A` = `FACTORIZATION_A.join( "\\times" )`\qquad\qquad`B` = `FACTORIZATION_B.join( "\\times" )`

Therefore the only factor of

out of our choices is `A`

. We can say that `B`

is divisible by `A`

.`B`

Which of the following numbers is a multiple of `B`?

`\large{`

`WRONGMULTIPLES_SORTED.join( "," )`}

`A`

`wrong`

The multiples of

are `B`

, `B`

, `B*2`

, `B*3`

.....`B*4`

In general, any number that leaves no remainder when divided by

is considered a multiple of `B`

.`B`

We can start by dividing each of our answer choices by

.`B`

`WRONG` \div `B` = `floor( WRONG / B )`\text{ R }`( WRONG % B )`

The only answer choice that leaves no remainder after the division is

. `A``\quad`

* `FACTOR`

= `B`

.`A`

We can check our answer by looking at the prime factorization of both numbers. Notice that the prime factors of

are contained within the prime factors of `B`

.`A`

`A` = `FACTORIZATION_A.join( "\\times" )`\qquad\qquad`B` = `FACTORIZATION_B.join( "\\times" )`

Therefore the only multiple of

out of our choices is `B`

. We can say that `A`

is divisible by `A`

.`B`
