To solve the question of whether 39 is a factor of 13962, we need to determine if 39 divides evenly into 13962 without leaving a remainder. If it does, then 39 is a factor of 13962. Here's how we can solve this problem:

1. Divisibility Rule: The easiest way to determine if a number is divisible by another number is by applying the divisibility rules. In this case, we need to check if 13962 is divisible by 39.

2. Division: We divide 13962 by 39 to check if it divides evenly.

- To do this, we can perform the long division method. Write 13962 as the dividend and 39 as the divisor. Begin dividing the numbers.

- Start with the leftmost digit of the dividend (1) and divide it by the divisor (39). The quotient will be less than 1, so we bring down the next digit (3), making it 13.

- Now, divide 13 by 39. The quotient will be 0, so we bring down the next digit (9), making it 139.

- Divide 139 by 39. The quotient will be 3, so we bring down the next digit (6), making it 36.

- Divide 366 by 39. The quotient will be 9, so we bring down the next digit (2), making it 92.

- Divide 926 by 39. The quotient will be 23, without any remainder.

3. Conclusion: Since the division ended with a quotient of 23 without any remainder, we can conclude that 39 is a factor of 13962.

Therefore, 39 is a factor of 13962.
