It is not a prime number.The 3 factors of 121 are 1, 11, and 121.Note: It is a square number (11 x 11), so it has an odd number of factors.The factor pairs of 121 are 1 x 121 and 11 x 11.The proper factors of 121 are 1 and 11 or,if the definition you are using excludes 1, the only proper factor is 11.The prime factors of 121 are 11 and 11. Note: There is repetition of these factors, so if the prime factors are being listed instead of the prime factorization, usually only the distinct prime factors are listed.The only distinct prime factor (listing each prime factor only once) of 121 is 11.The prime factorization of 121 is 11 x 11 or, in index form (in other words, using exponents), 112.NOTE: There cannot be common factors, a greatest common factor, or a least common multiple because "common" refers to factors or multiples that two or more numbers have in common.
11 * 11 * x * x
7x2 - 847 [First factor out a 7] 7(x2 - 121) [Now factor it totally] 7(x + 11)(x - 11) x = 11 and -11

1, 5, 7 and 35 are the factors of 35. The proper factors are 5 and 7.
11 has no factors except 1(11 is a prime number)
The proper factors of 99 are: 1, 3, 9, 11, 33. A proper factor is any factor of the number that is not itself.
No, 11 is itself a prime so no prime number can be a proper factor of 11.
a proper factor is a factor.
The only proper factors of 77 are 7 and 11. 11 isn't a factor of 259 but 7 is, so the answer is 7.
No. Prime numbers don't have proper factors.
