FAQs

Q1: What is the highest power of 2 that divides 38729?

A1: To find the highest power of 2 that divides 38729, we need to determine the largest exponent \(k\) such that \(2^k\) is a factor of 38729. Upon checking, we see that \(2^1 = 2\) is a factor but \(2^2 = 4\) is not because 38729 is an odd number. Therefore, the highest power of 2 that divides 38729 is \(2^1\).

Q2: How would you verify if 38729 is a prime number?

A2: To verify if 38729 is a prime number, we would need to check divisibility by all prime numbers up to the square root of 38729 (approximately 196.8). Since we've already identified factors like 7 and 467 earlier, it confirms that 38729 is not a prime number as it has multiple distinct factors other than 1 and itself.
