Proof true or false: For all integers a,b,and c,if ab|c then a|c and b|c

olya-2409 [2.1K]

Answer with explanation:

It is given that for three integers , a, b and c, if

$\frac{ab}{c}\rightarrow then, \frac{a}{c} \text{or} \frac{b}{c}$

Since , a b is divisible by c , following are the possibilities

1.→ a and b are prime integers .Then , c will be prime number either equal to a or b.

2.→a and b are not prime integers ,then any of the factors of a or b will be equal to c.For example:

⇒a=m × n

b=p × q× c

or,

⇒a=u×v×c

b=s×t

So, whatever the integral values taken by a, and b, if $\frac{ab}{c}$ then either of $\frac{a}{c} \text{or} \frac{b}{c}$ is true.
