Video Solution

Step-by-Step Solution

To solve this problem, we'll follow these steps:

  • Step 1: Perform the prime factorization of 350 350 .
  • Step 2: Identify all possible combinations of the factors.
  • Step 3: Verify each step to ensure all factors are included.

Now, let's work through each step:
Step 1: Perform the prime factorization of 350 350
The number 350 350 is even, and hence divisible by 2 2 :
350÷2=175 350 \div 2 = 175
Next, 175 175 ends in 5 5 , indicating it is divisible by 5 5 :
175÷5=35 175 \div 5 = 35
Next, 35 35 is also divisible by 5 5 (it ends in 5 5 ):
35÷5=7 35 \div 5 = 7
Finally, 7 7 is a prime number.
Thus, the prime factorization of 350 350 is 2×52×7 2 \times 5^2 \times 7 .

Step 2: Identify all possible combinations of factors.
Using the prime factors, combine them to list all factors of 350 350 :
- 1 1 (trivial factor)
- 2 2
- 5 5
- 7 7
- 2×5=10 2 \times 5 = 10
- 2×7=14 2 \times 7 = 14
- 5×5=25 5 \times 5 = 25
- 5×7=35 5 \times 7 = 35
- 2×52=50 2 \times 5^2 = 50
- 2×5×7=70 2 \times 5 \times 7 = 70
- 52×7=175 5^2 \times 7 = 175
- 350 350 (the number itself)

Step 3: Verify each step.
Verify each combination using basic multiplication to ensure accuracy.

Therefore, all the factors of 350 350 are:
1,2,5,7,10,14,25,35,50,70,175,350 1, 2, 5, 7, 10, 14, 25, 35, 50, 70, 175, 350 .
