Prime Factorisation of 68:
• The first step is to divide the number 68 with the smallest prime factor, i.e. 2 and divide the output again by 2 till you get a fraction or odd number.
68 ÷ 2 = 34
• Now, again divide 34 by 2.
34 ÷ 2 = 17
• Now, we know 17 is a prime number and it has only two factors; 1 and 17. Therefore, we cannot continue with the division method further.
Therefore, the prime factors of 64 are 2 and 17.
