The GCF is 26.
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 common factors of 182 and 442 are: 1, 2, 13, and 26
51.

221, 442, 663
The GCF of 78 and 663 is: 39
51
The greatest common factor (GCF) is 1.
62 and 442's highest common factor is two.
GCF = 26. 78 = 2 x 3 x 13. 442 = 2 x 13 x 17. Common factors are 2 & 13. 2x13=26.
The GCF is 226.
221, 442, 663, 884 and so on.
The GCF is 26.
221, 442, 663, 884, 1105.
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.
