If the number represented by the last three digits of a whole number is divisible by 8, then the number itself is divisible by 8. The final answer is found by including all of the factors from the “circled leaves” at the end of each branch of the tree, which yields the same result, namely 24 = 2 · 2 · 2 · 3.

Notice that the whole number 1 is not considered to be a prime number, and the whole number 2 is the first prime and the only even prime number.

This can be found using either the tree method or the ladder method. The tree method involves writing the factors below the number and connecting them to the number with small line segments. The ladder method involves dividing the given number by its smallest prime factor. The composite number is the product of all the primes used in either method, which should give the same result.

The Greatest Common Factor (GCF) is the largest positive integer that divides two or more numbers without a remainder, with applications in simplifying fractions and algebraic expressions. Methods for finding factors and calculating the GCF include listing factors, prime factorization, and the Euclidean algorithm.

The least common multiple (LCM) of a group of whole numbers is the smallest whole number that each of the given whole numbers divides into without a remainder. The LCM of two or more whole numbers is the smallest whole number that each of the given numbers divides into without a remainder.

The final answer is found by including all of the factors from the “circled leaves” at the end of each branch of the tree, which yields the same result, namely 24 = 2 · 2 · 2 · 3. This result guarantees that if the prime factors are ordered from smallest to largest, everyone will get the same result when breaking a number into a product of prime factors.
