A student says the prime factors of 17 are 1 and 17. Is the student correct? explain.

Correct

Step-by-step explanation:

1. Factors

Are whole numbers that can divide the number completely.

2. Prime number

Number of factors that can be express in form of prime factorisation.

Prime factorisation of a number can be done by repeated division by prime numbers (number is written as the product of its prime factors)

For example, 17

List of factors, 1 and 17

Prime number, 17

Prime factorisation, 1×17=17

So why prime numbers cannot be express in form of prime factorisation?

Because, a prime number can only be divided by 1 or itself, so it cannot be factored any further. Not like the other number.

Brainliest would be appreciated :)

62.5 paisa

step-by-step explanation:

4000*70 = 280000

280000-(2000*90) = 100000

4000-2400 = 1600

100000/1600 = 62.5
