WebOct 18, 2024 · Let’s find out the prime factors of 245 by division method. First we’ll divide 245 by the smallest prime number 2. But 2 can’t divide 245 exactly. So, we have to move towards the next one. As you can guess, no smaller prime number than 5 can divide 245 evenly. By dividing 245 by 5, we get 49 as the quotient. Web1225 ÷ 5 = 245; 245 ÷ 5 = 49; Further dividing 49 by 5 gives a non-zero remainder. So we stop the process and continue dividing the number 49 by the next smallest prime factor. We stop ultimately if the next prime factor doesn't exist or when we can't divide any further. So, the prime factorization of 1225 can be written as 5 2 × 7 2 where 5 ... custom car window sticker maker
