The factors of 243 are 1, 3, 9, 27, 81, and 243.

The common factor is: 1

The factors of 81 are 1, 3, 9, 27, and 81. The factors of 243 are 1, 3, 9, 27, 81, and 243. The common factors of 81 and 243 are 1, 3, 9, 27, and 81. Therefore, the least common factor (the smallest common factor) is 1.

The only common factor is: 1

1, 3, 9, and 27

There is neither a greatest common factor nor common factors of a single number, such as 243, because there cannot be any form of common factor without two or more numbers to compare. Common factors are factors that the numbers being compared have in common. The greatest common factor is the largest factor that all the numbers being compared have in common. Thus, since there are not two or more numbers to compare, there are neither common factors nor a greatest common factor.

243 is a composite number because it has factors other than 1 and itself. It is not a prime number.The 8 factors of 243 are 1,2,3,4,9,27,81, and 243.The factor pairs of 243 are 1 x 243, 3 x 81, and 9 x 27.The proper factors of 243 are 1, 3, 9, 27, and 81 or,if the definition you are using excludes 1, they are 3, 9, 27, and 81.The prime factors of 243 are 3, 3, 3, 3, and 3. 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 factor (listing each prime factor only once) of 243 is 3.The prime factorization of 243 is 3 x 3 x 3 x 3 x 3 or, in exponential form, is 35.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.

The factors of 243 are: 1 3 9 27 81 243

All factors of 243 are: -243, -81, -27, -9, -3, -1, 1, 3, 9, 27, 81, and 243.

The greatest common factor of 7 and 243 is 1. Prime factorizations: 7 = 7 243 = 3 x 3 x 3 x 3 common factors - no primes, so only common factor is 1: 7 x 1 = 7 243 x 1 = 243

-243 is a composite number because it has factors other than 1 and itself. It is not a prime number.The 12 factors of -243 are ±1, ±3, ±9, ±27, ±81, and ±243.The prime factors of -243 are -1, 3, 3, 3, 3, and 3. Technically, -1 is not a prime factor (it is a unitary factor), but it is included here because the number is negative. 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 factor (listing each prime factor only once) of -243 is 3.The prime factorization of -243 is -1 x 3 x 3 x 3 x 3 x 3 or, in index form (in other words, using exponents), -1 x 35.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.

THe LCM of 123 and 243 is 9963 The first step in working out the least common multiple of two numbers is to express them as their prime factors. In this case 123 and 243 can be broken down as follows: 123 = 41x3 243 = 3x3x3x3x3 The next step is to identify and discard the duplicates of any common factors. In this case, both numbers have a 3 as a prime factor, so we can discard one of these. Take all the other prime factors (41, 3, 3, 3, 3 and 3) and multiply them together to get the LCM: 41x3x3x3x3x3=9963
