Find factors and multiples of numbers, identify common factors and common multiples, and understand prime and composite numbers
Factors divide exactly into a number with no remainder. Multiples are found by multiplying a number by positive integers.
Understanding factors and multiples builds foundation for fractions, ratios, prime factorization, and algebraic concepts.
Factor and multiple knowledge helps with grouping problems, sharing tasks, and finding patterns in real situations.
Factor and multiple skills enable quick identification of equivalent fractions and simplification of calculations.

What students often do wrong:
Students often confuse factors and multiples, thinking factors are bigger than the original number, or forgetting that 1 and the number itself are always factors.
To remember: Factors divide INTO a number (usually smaller), multiples are found BY multiplying (usually bigger).
Memory tip: Factors are "friendly" numbers that fit exactly inside! Multiples are "mountains" - they grow bigger!
Use real-world examples like organizing students into equal groups to make factors and multiples more concrete and memorable. Always start with systematic approaches: for factors, test divisibility; for multiples, use multiplication tables.
