The product of three consecutive numbers is 21,924. What is the smallest number out these numbers?

Natasha_Volkova [10]

Answer:

27

Step-by-step explanation:

Let the middle number be x.

(x - 1)(x)(x + 1) = 21,924

You can solve that equation, or you can use logic.

The 3 numbers are going to be close to the cubic root of 21,924.

cubic root of 21,924 = 27.988 or approx 28.

Try 27, 28, 29

27 * 28 * 29 = 21,924

Answer: 27

Sergio [31]

Step $1$

<u>Find the factors of each number</u>

we know that

$32=2^{5} \\48=2^{4}*3\\72=2^{3}*3^{2}$

Step $2$

<u>Find the greatest common factor (GCF)</u>

the GCF is equal to----------> $2^{3}=8$

therefore

<u>the answer is</u>

The GCF is $8$
