32 x 29 = 261

261 is a composite number because it has factors other than 1 and itself. It is not a prime number.The 6 factors of 261 are 1, 3, 9, 29, 87, and 261.The factor pairs of 261 are 1 x 261, 2 x 87, and 9 x 29.The proper factors of 261 are 1, 3, 9, 29, and 87 or,if the definition you are using excludes 1, they are 3, 9, 29, and 87.The prime factors of 261 are 3, 3, and 29. 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 distinct prime factors (listing each prime factor only once) of 261 are 3 and 29.The prime factorization of 261 is 3 x 3 x 29 or, in exponential form, 32 x 29.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.

Yes. An easy way to see if any number can be divided by 3, is to add up the digits in the number. If the digits in the number add up to a multiple of three, it is divisible by 3. 261 --> 2 + 6 + 1 = 9 (9 is divisible by 3, so in turn 261 is also) 210 --> 2 + 1 + 0 = 3 (3 can be divided by itself, so 210 is divisible by 3) 8349 --> 8 + 3 + 4 + 9 = 24 (24/3=8, so 8349 is divisible by 3)
