487872

487872 is a positive integer that lies between 487000 and 488000. It is even and composite, with multiple small prime factors. In number theory, it serves as an example of a highly factorable number due to its nontrivial prime decomposition.

Its prime factorization is 2^6 × 3^2 × 7 × 11^2, which equals 64 × 9 × 7 × 121, or 487872. Because of this factorization, the number is divisible by many integers, including 2, 3, 6, 7, 9, 11, 12, 14, 18, 22, 28, 33, 36, 44, 63, 77, 99, and 121, among others. The highest power of two dividing 487872 is 2^6, i.e., 64; it is not divisible by 128.

In decimal notation, the digits are 4, 8, 7, 8, 7, 2, showing a pattern of two 8s and two 7s with a 4 and a 2. The number is not a palindrome in base 10. It is also a Harshad (Niven) number, since the digit sum is 4+8+7+8+7+2 = 36 and 487872 ÷ 36 = 13552.
