Since 4 x 7 is 28, you know that 7 isn't a factor of 29. Since 29 is a prime number, you know that 7 isn't a factor of it. To be perfectly sure, divide 7 into 29. If the answer is an integer, it's a factor.
The only number that could be both a factor and a multiple is 7 itself.
Because 7 is a factor of 28 and 63 and 7 is a prime number.
Technically, 7 is a prime number so itself and 1 are the only candidates. If you consider 1 to be a factor, then the only common factor is 1, which is not useful in any application I know.
The number 7 is a factor of 7,14,21,28,35,42,49,56,63,70,77,84,91,98,105 or anything multiplied by 7.
Since 4 x 7 is 28, you know that 7 isn't a factor of 29. Since 29 is a prime number, you know that 7 isn't a factor of it. To be perfectly sure, divide 7 into 29. If the answer is an integer, it's a factor.
You know that 7 isn't a factor of 291 because the quotient of 291 and 7 isn't a whole number.
all perfect cubes (any number powered by 3) by adding or subtracting 1 become factor of 7 except base number as 7 and its factors.
The only number that could be both a factor and a multiple is 7 itself.
Since the number 7 is a prime number and not a factor of 26, the greatest common positive integer factor of 7 and 26 is 1.
7 because 7and 1 are the only factor since 7 is a prime number. 1 isn't a prime or composite number so it is 7.
Factors come in pairs. If you know one factor, divide it into the number. The answer will be another factor.
7-c
1 and 7

No
I don't know where you saw that. 7 is a factor of 350.
