Properties of divisibility theorem
WebNov 4, 2024 · If you have the number 5 as the divisor, the dividend is divisible by divisor if the last digit is 0 or 5.For example, the number 30 is divisible by 5 because the last digit in 30 is 0. If you have... WebAug 28, 2011 · Theorem Let fn be an integer sequence such that f0 = 0, f1 = 1 and such that for all n > m holds fn ≡ fk fn − m (mod fm) for some k < n, (k, m) = 1. Then (fn, fm) = f ( n, m) Proof By induction on n + m. The theorem is trivially true if n = m or n = 0 or m = 0. Assume wlog n > m > 0. Since k + m < n + m, by induction (fk, fm) = f ( k, m) = f1 = 1.
