Smallest prime factor of 42

WebbStep 1: Find the smallest prime number that is a factor of at least one of the numbers, 42 and 49. Write this prime number (2) on the left of the given numbers (42 and 49), separated as per the ladder arrangement. Step 2: If any of the given numbers (42, 49) is a multiple of 2, divide it by 2 and write the quotient below it. WebbA prime factor is not always less than the square root as you could see with the $14 = 2 \times 7$ as a counter example, since $7 \gt \sqrt14$. But you can show that when the number is not prime, the smallest prime divisor less than the number itself is less than or equal to the square root.
