Answer 2

Answer:

2 x 3 x 5 x 7 + 13 exists a composite number.

Step-by-step explanation:

The numbers which can be induced by multiplying the two least positive integers and containing at least one divisor other than the number ‘1’ exist comprehended as composite numbers. These numbers still have more than two elements.

Properties of composite numbers

• Composite numbers include more than two elements.
• Composite numbers stand evenly divisible by their factors.
• Each composite number as exists as a character itself.
• The least composite number exists 4.
• Each composite number will have at least two prime numbers as its factors (Eg. 10 = 2 x 5, where 2 and 5 are prime numbers)
• Composite numbers exist divisible by other composite numbers also.

2 x 3 x 5 x 17 + 13

= 30 x 17 + 13

= 510 + 13

= 523.

Here 523 exists as a composite number.

Therefore, 2 x 3 x 5 x 7 + 13 exists a composite number.
