Question

Why is 5x7x11+7 is a composite number ​

Answer 1

$\huge \bold{hey \: there}$

➡ 5×7×11+7

Taking 7 as common,

➡7(5×1×11+1)

➡7×56

Since, the number formed by multiplying these numbers will have more than 2 factors, hence it will be a composite number.

Answer 2

Answer:

$5\times7\times11 + 7$ is a composite number as it has divisors other than $1$ and the number itself.

Step-by-step explanation:

Composite numbers:-

• The numbers that have more than two factors are called composite numbers.
• In other words, the numbers that have divisors other than 1 and the number itself are called composite numbers.

Step 1 of 2

Consider the given expression as follows:

$5\times7\times11 + 7$

Simplify as follows:

⇒ $7(5\times11+1)$

⇒ $7(55+1)$

⇒ $7\times56$

⇒ $392$

Step 2 of 2

The factors of the number 392 are,

$392=2\times2\times2\times7\times7$

Observe that the number $392$ has more than $2$ factors or the number $392$ has divisors other than $1$ and the number itself.

Therefore, $5\times7\times11 + 7$ is a composite number.
