WebbIf $a$ divides $b$, then $b = a \cdot k$ for some integer $k$. Thus if you multiply both sides by $c$, we get the desired $bc = akc$. On the other hand, if $ac$ divides $bc$, then $bc = akc$ for some integer $k$. Dividing both sides by $c$ yields the desired result.

WebbFor all integers a, b and c, if a divides b and b divides c, then a divides c. Proof: We start from hypothesis by supposing a, b, and c are particular but arbitrarily chosen integers such that a divides b and b divides c. Our next step is to define our goal clearly, which is to show that a divides c. In other words, we need to show that WebbYes, it’s correct. However, if you had the condition that a was relatively prime to b, then the statement would be true. This is a consequence of Bezout’s Identity.

Webb17 maj 2024 · subtracting the equations: a * n - a* m = b - c a (n - m) = b - c <-- distributive since n and m are integers, n - m is also an integer by closure property of integer division. So then there is an integer t = n-m a* t = b - c therefore, t = (b-c)/a which means a divides b - c for integer t Upvote • 0 Downvote Add comment Report WebbAssume √3 is irrational. Then there exists an integer A and B such that √3 = A/B, with A/B reduced to lowest terms. Thus, 3 = A²/B² => 3B² = A². So, A² is a multiple of 3 which implies that A is a multiple of 3. Hence, A=3k for some integer k. This means that 3B²=A² = (3k)² = 9k², so B² = 3k² is a multiple of 3 and thus so is B.

If a and b are integers such that a ≠ 0, then we say " a divides b " if there exists an integer k such that b = ka. If a divides b, we also say " a is a factor of b " or " b is a multiple of a " and we write a ∣ b. If a doesn’t divide b, we write a ∤ b. For example 2 ∣ 4 and 7 ∣ 63, while 5 ∤ 26.
