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

Answer with explanation:

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

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 then either of   is true.
