1,3,7,9,13,21,27,39,63,91,117,189,273,351,819,2457
2,457 is not prime (so it is composite) because 2,457=3x3x3x7x13
To find the prime factors, start with the obvious ones. 4914 is even so divide it by 2 and we get 2457. The digit sum of this is 9, so divide by 9 (3x3) and get 273. The digit sum divides by 3 so divide by 3 and get 91, which is 13x7. So in total we have 2, 3, 3, 3, 7 and 13 as the prime factors of 4914
2985 + 2457 = 5442
2457 x 8 = 19656
The factors of 245 are 1, 5, 7, 35, 49, and 245.The prime factors of 245 are 5, 7, and 7.Determining the prime factors:The process of prime factorization is one of repeated division by primes, while obtaining a quotient without a remainder, until the process yields a quotient of 1245 is not divisible by 2 or by 3245 ÷ 5 = 49 ................................. 5 is a prime factor of 24549 is not divisible by 549 ÷ 7 = 7 ..................................... 7 is a prime factor of 2457 ÷ 7 = 1 ....................................... 7 is a prime factor of 245So the prime factorization of 245 are 5 x 7 x 7 or, in index form (in other words, using exponents), 5 x 72.
Prime factors are factors that are also prime numbers.
To work it out you'll need to break it down by halving it, by 3's, 5's, 7's etc... until you can't break it down no more. Your final answer should consist of 2x2x3x7 etc... and when you times them all together you should get 2457.
