Divide 7 into 291. If it comes out evenly, it's a factor. It doesn't, so it's not.
9 is paired with 6 to give you 54. 9x6 is 54.
No.
7. 7 x 5 = 35
It is not possible to give a sensible answer to this question. The highest common factor (HCF) refers to a factor that is COMMON to two or more numbers. You have only one number in the question!
7 x 41.57142857 = 291
17x1=7
Divide 7 into 291. If it comes out evenly, it's a factor. It doesn't, so it's not.
7 x 7 = 49
Divide 7 into 291. If the result is an integer, 7 is a factor.

There isn't an easy test for 7. You have to divide it. 7 is not a factor of 291.
You know that 7 isn't a factor of 291 because the quotient of 291 and 7 isn't a whole number.
Divide 291 by 7 and see if you get a whole number or is there a remainder. If it is not a whole number, then it is not a factor. 7 goes into 291 41 times with a remainder of 4, so it is not a factor.
No.
