Question

choose all the numbers that 84 is divisible by

Answer 1

to find the divisors of 84 we have to divide 84 by the lowest number is possible so in this case is 2 so:

$\frac{84}{2}=42$

Again by 2:

$\frac{42}{2}=21$

the next number is 3 so:

$\frac{21}{3}=7$

and 7 is only divisible by 7 so:

$\frac{7}{7}=1$

Now the divisors will be all posible numbers that we can made by miltiply: 7,3,2 and 2 plus 1 and 84 so in this case are:

$1,2,3,4,6,7,12,14,21,28,42\text{ and 84}$
