Answer 1

1824274 is the composite number

Answer 2

17 × 41 × 43 × 61 + 43

Taking 43 common from both the terms

43 ( 17 × 41 × 61 + 1)

43 ( 42517 + 1)

43 × 42518

We know that a number is composite if it has two or more factors other than 1.

Here we can see that the given number (17 × 41 × 43 × 61 + 43) can be expressed as product of two numbers ∴ Given number is composite.

(You may factorize 42518 further to get more factors of given number, which is not accessory here)
