WebIn base 10, the digital root of a nonzero triangular number is always 1, 3, 6, or 9. Hence, every triangular number is either divisible by three or has a remainder of 1 when divided by 9: 0 = 9 × 0 1 = 9 × 0 + 1 3 = 9 × 0 + 3 6 = 9 × 0 + 6 10 = 9 × 1 + 1 15 = 9 × 1 + 6 21 = 9 × 2 + 3 28 = 9 × 3 + 1 36 = 9 × 4 45 = 9 × 5 55 = 9 × 6 + 1 WebMar 26, 2024 · Topic: Project Euler Problem 12: Highly divisible triangular number.
