6912 prime factorisation

Solution

The prime factorization of 6912 is:

6912=28×336912 = 2^8 \times 3^3

Steps:

  1. Start dividing by the smallest prime number, 2: 6912÷2=34566912 \div 2 = 3456
  2. Divide 3456 by 2: 3456÷2=17283456 \div 2 = 1728
  3. Continue dividing by 2: 1728÷2=864,864÷2=432,432÷2=2161728 \div 2 = 864, \quad 864 \div 2 = 432, \quad 432 \div 2 = 216 216÷2=108,108÷2=54,54÷2=27216 \div 2 = 108, \quad 108 \div 2 = 54, \quad 54 \div 2 = 27
  4. Now divide 27 by the next smallest prime number, 3: 27÷3=9,9÷3=3,3÷3=127 \div 3 = 9, \quad 9 \div 3 = 3, \quad 3 \div 3 = 1 Thus, the prime factorization of 6912 is 28×332^8 \times 3^3.
