7 doesn't have an easy test. But when I see that 291 is made up of 280 + 11, I know that 7 is not a factor.
The GCF is 291.
291
Factors of 35 are: 1, 5, 7, 35Factors of 49 are: 1, 7, 49So, the highest common factor is 7.
No. 354/7 = 50 remainder 4
Divide 7 into 291. If it comes out evenly, it's a factor. It doesn't, so it's not.
None. 291 is not divisible by 7 and so you cant have a whole number factor pair with 7
Divide 7 into 291. If the result is an integer, 7 is a factor.
No - 7 is neither a multiple or factor of 291.
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.
7 doesn't have an easy test. But when I see that 291 is made up of 280 + 11, I know that 7 is not a factor.
No.
no because if you divide you get 41.57 and that is not a whole number.
Divide it. It isn't.
