12. Higher Order Thinking Find all the
factors of 38, 39, and 40. Do they have
any factors in common? Explain how you
can tell if some numbers have factors in
common without finding the factors.
Answer:
they are all divisible by 1
Step-by-step explanation:
38 divided by 1 is 38. 39 divided by 1 is 39. and 40 divided by 1 is 49
Step-by-step explanation: The commutative property of multiplication states that changing the order of the factors does not change the product.
Example:
4 × 10 ≈ 10 × 4
If we multiply both these numbers together, we will get the same answer which is 40. This means that 4 × 10 must be equal to 10 × 4.
Example:
3 × 2 ≈ 2 × 3
Both of the answers will equal 6 which means that they are equal to each other.
