1225 is a composite number because it has factors other than 1 and itself. It is not a Prime number.

The 9 factors of 1225 are 1, 5, 7, 25, 35, 49, 175, 245, and 1225. Because 1225 is a square number (35 x 35), it has an odd number of factors.

The factor pairs of 1225 are 1 x 1225, 5 x 245, 7 x 175, 25 x 49, and 35 x 35.

The proper factors of 1225 are 1, 5, 7, 25, 35, 49, 175, and 245 or,

if the definition you are using excludes 1, they are 5, 7, 25, 35, 49, 175, and 245.

The prime factors of 1225 are 5, 5, 7, and 7. 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 2 distinct prime factors (listing each prime factor only once) of 1225 are 5 and 7.

The prime factorization of 1225 is 5 x 5 x 7 x 7 or, in index form (in other words, using exponents), 52 x 72.

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.
