Question

1. Do all the factors of a given number divide the number exactly? Find the

factors of 28 and verify by division.

2. 3 is a factor of 15 and 24. Is 3 a factor of their difference also?​

Answer 1

Answer:

1. True

Factors of 28 are 1, 2, 4, 7, 14, 28.

Now Verification:-. 1 divides 28 exactly.

So, 2 divides 28 exactly.

So, 4 divides 28 exactly.

So, 7 divides 28 exactly.

So, 14 divides 28 exactly.

2. Yes, 3 is a factor of difference of these numbers.

Answer 2

Answer:

1. factor of 28 - 2,4,7,14,28

Therefore, no.divisible to any no. it is not possible that it should divisible. by all numbers

2. 3 is a factor of 15 and 24 but it is not important that it should be divisible by 3
