Question

Which of the given numbers should be subtracted from 530 so that it becomes prime?

Answer 1

But numbers are not given to us .

Answer 2

Answer:

1 should be subtracted from 530 so that it becomes prime

Step-by-step explanation:

A prime number is a whole number greater than 1 whose only factors are 1 and itself

We are given a number 530

Subtracting 1 from 530

⇒ 530 - 1 = 529

Now,

529 has two factors 1 and 529 itself .

So, 529 is a prime number

Hence,

 1 should be subtracted from 530 so that it becomes prime
