No
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.
not necessarily.
A factor of a number is any number which the original number can be divided by evenly. In this case, 29 divides by 7 to give 4 remainder 1. This remainder means that 29 does not divide evenly by 7. Thus 7 is not a factor of 29.
No, this statement is not true. 21 is an example of why this is not true.
No. Only 14 and multiples of 14 have both 7 and 2 as factors.
For 2 to be a factor, the number has to be even. If you multiply two odd numbers together, you get an odd number. 7 is odd, so if I multiply it by any odd number, I will get a number that doesn't have 2 as a factor (e.g. 7x5=35 which doesn't have 2 as a factor). Thus, the answer to the question is "no," not all multiples of 7 have 2 as a factor.
A factor is any number which the original number can divide into evenly. A common factor is a number which is a factor of both numbers being considered. In this case, we have 1. The only nunmber 1 can divide evenly into is 1, and thus this is the only common factor between it and 7. Therefore, the GCF of 1 and 7 is 1.
The greatest factor of any number is the number itself. The second greatest factor of any even number is half the number. The second greatest factor of any composite number is the number divided by its smallest prime factor. The second greatest factor of any prime number is 1.
GCF requires a COMMON factor. You cannot have a COMMON factor with only one number - you require at least TWO numbers.To have a greatest COMMON factor of 7, the numbers must have only 7 as a common prime factor.Thus, for example 7, 12474, 3183837475 & 20106594977 have a Greatest COMMON factor of 7.
The concept of a factor makes proper sense only in the context of integers. Otherwise, any non-zero number can be factor of any other number. For example, radical 7 is a factor of radical 18 since radical(180) = radical(7) * radical (18/7)
Any multiple of 105.
The only number that could be both a factor and a multiple is 7 itself.
