Question

2.
Find the number of different divisors of 400, besides
unity and the number itself.
a) 15 b) 14 c)13 d) 122​

Answer 1

Answer:

There are 13 different divisors of 400, besides unity and the number itself.

Step-by-step explanation:

Given number is 400

We need to find the number of different divisors

We know that divisor is a number that completely divides the given number.

Therefore, the numbers that divide 400 completely are:

1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, 400

It is mentioned that we do not have to count 1 and 400

Therefore, the remaining numbers are

2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200

Therefore, there are 13 different divisors of 400, besides unity and the number itself.

Answer 2

The right option that answers the given question correctly is Option C) 13.

Step-by-step explanation:

• As the name suggests, a divisor is a number which can be divided by another number to determine the product. In other words, a divisor must be bigger than the number you are dividing.
• A divisor is a device that divides a number by itself or a number by a fraction, and then multiplies the result by a number.
• Divisors of 400 other than 1 and itself are as follows:

                2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200

• That makes it a total of 13 divisors.
