7. the number will be divisible by factors of 4 and 7 and product of 4 and 7 as 4 and 7 are coprime.

1,2,4,7,28

Answer 2

6.th Solution =

Factor of 18 = 1, 2, 3, 6, 9 and 18.

I have to explain you another question that

Q. A number is divisible by 12. By what other numbers will that number be divisible?

Step by step explanation:-

First you have to find the Factor of thats number, then you will get your answer.

Factor of 12 = 1,2,3,4,6,12 .

Therefore, the number also be divisible by = 1,2,3,4 and 6.

7.th. Solution =

• Therefore, both numbers are co-prime numbers. So the number is divisible by the product - 4 × 7 = 28 . The number must be divisible by 28.

Step by step explanation =

First you have to check that the number is co- prime . Then you have to find the product of that number . and the product is the answer.

You have to write the language of solution that I write .
