1. Decimal Representation:
- 66666666 is simply the number 66,666,666 in decimal form.
2. Scientific Notation:
- It can be written as $ 6.6666666 \times 10^7 $.
3. Prime Factorization:
-
66666666 is an even number, so it is divisible by 2.
-
Dividing by 2: $ 66666666 \div 2 = 33333333 $
-
33333333 is odd, so divide by 2 again: $ 33333333 \div 2 = 16666666.5 $ → not an integer.
-
So, 66666666 = $ 2 \times 33333333 $
-
33333333 is also even, so divide by 2: $ 33333333 \div 2 = 16666666.5 $ → not an integer.
-
So, 33333333 = $ 2 \times 16666666.5 $ → not valid.
Wait, this suggests that 66666666 is not a prime number, but it is divisible by 2 and 3.
Let's check if it's divisible by 3:
- Sum of digits: $ 6 + 6 + 6 + 6 + 6 + 6 + 6 + 6 = 48 $
- 48 is divisible by 3, so 66666666 is divisible by 3.
So, 66666666 = $ 2 \times 3 \times 11111111 $
Now, 11111111 is a well-known number in mathematics, and it is divisible by 101.
So, 11111111 = $ 101 \times 109999 $
Therefore, the prime factorization of 66666666 is: $$ 66666666 = 2 \times 3 \times 101 \times 109999 $$
