The factors of 245 are 1, 5, 7, 35, 49, and 245. The pairs are 1*245, 5*49, and 35*7. The prime factorization of 245 is 5*7*7 or in exponential form 5*72. The prime factors are 5 and 7.
2695 is a composite number because it has factors other than 1 and itself. It is not a prime number.The 12 factors of 2695 are 1, 5, 7, 11, 35, 49, 55, 77, 245, 385, 539, and 2695.The factor pairs of 2695 are 1 x 2695, 5 x 539, 7 x 385, 11 x 245, 35 x 77, and 49 x 55.The proper factors of 2695 are 1, 5, 7, 11, 35, 49, 55, 77, 245, 385, and 539 or,if the definition you are using excludes 1, they are 5, 7, 11, 35, 49, 55, 77, 245, 385, and 539.The prime factors of 2695 are 5, 7, 7, and 11. 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 3 distinct prime factors (listing each prime factor only once) of 2695 are 5, 7, and 11.The prime factorization of 2695 is 5 x 7 x 7 x 11 or, in index form (in other words, using exponents), 5 x 72 x 11.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 2,695 are:1, 5, 7, 11, 35, 49, 55, 77, 245, 385, 539, 2695.
All factors of 245: 1, 5, 7, 35, 49, 245.

composite, 5 can go into it
245 is not prime. Composite: (5 x 49 or 5 x 7 x 7) Also you can automatically determine a number as composite if: it ends with 2, 4, 6, 8, and 0: multiples of 2; or it ends with 5: multiples of 5.
39.05-245 = -205.95
It is: 33+211+1 = 245
