A factor is a divisor - a number that will evenly divide into another number. One way to determine the common factors and greatest common factor is to find all the factors of the numbers and compare them. The factors of 169 are 1, 13, and 169. The factors of 14365 are 1, 5, 13, 17, 65, 85, 169, 221, 845, 1105, 2873, and 14365. The common factors are 1, 13, and 169. This would mean that the greatest common factor is 169.
Factors for 442: 1, 2, 13, 17, 26, 34, 221, 442 Factors for 663: 1, 3, 13, 17, 39, 51, 221, 663 Common Factors: 1, 13, 17, 221

663 is a composite number because it has factors other than 1 and itself. It is not a prime number.The 8 factors of 663 are 1, 3, 13, 17, 39, 51, 221, and 663.The factor pairs of 663 are 1 x 663, 3 x 221, 13 x 51, and 17 x 39.The proper factors of 663 are 1, 3, 13, 17, 39, 51, and 221 or,if the definition you are using excludes 1, they are 3, 13, 17, 39, 51, and 221.The prime factors of 663 are 3, 13, and 17.The 3 distinct prime factors (listing each prime factor only once) of 663 are 3, 13, and 17.The prime factorization of 663 is 3 x 13 x 17.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 221 are 1, 13, 17, and 221.
The greatest common factor of 494 and 221 is 13.
The GCF is 221
1 and 221, respectively.
13 is the greatest common factor of 208, 221, 234, 247, 260, 273, and 286.
208 and 221, among others.
The first step in finding the greatest common factor is to break the numbers down into their prime factors: 663=3x13x17 1547=7x13x17 The next step is to identify any common factors. In this case, the common prime factors are 13 and 17. To find the greatest common factor we multiply these together: 13x17=221 So 221 is the GCF of 663 and 1547.
OK suppose this is your questionwhat is the least common multiple of 21 and 16?21 is 3 times 716 is 2 to the 4th power (2 times 2 times 2 times 2)So these numbers have no factors in common.Therefore, to find the least common multiple, you multiply them together:21 x 16 = 126 + 210 = 336 hope this helps give more detail you only put 21 whats the other number?
A factor is a divisor - a number that will evenly divide into another number. One way to determine the common factors and greatest common factor is to find all the factors of the numbers and compare them. The factors of 169 are 1, 13, and 169. The factors of 14365 are 1, 5, 13, 17, 65, 85, 169, 221, 845, 1105, 2873, and 14365. The common factors are 1, 13, and 169. This would mean that the greatest common factor is 169.
1, 13, 17, and 221.
221 has two factor pairs: 13 * 17 and [perhaps redundantly] 1 * 221
Factors for 442: 1, 2, 13, 17, 26, 34, 221, 442 Factors for 663: 1, 3, 13, 17, 39, 51, 221, 663 Common Factors: 1, 13, 17, 221
The greatest common factor (GCF) is often also called the greatest common divisor (GCD) or highest common factor (HCF). Keep in mind that these different terms all refer to the same thing: the largest integer which evenly divides two or more numbers.The greatest common factor of 94 and 141 is 47
