1230000

1230000 is a natural number that follows 1229999 and precedes 1230001. In decimal notation it is written as 1,230,000 and is equal to 123 × 10,000 or 1.23 × 10^6.

Its prime factorization is 2^4 × 3 × 5^4 × 41. Equivalently, 1,230,000 = 16 × 3 × 625 × 41 = 123 × 10,000. This shows that the number is divisible by 2, 3, 5, and by 10,000, among other factors.

Because the last four digits are zeros, 1,230,000 is divisible by 16 and by 625, hence by 10,000 (since 16 and 625 are coprime). It is not divisible by 32, as the highest power of two in its factorization is 2^4. The sum of its digits is 1+2+3+0+0+0+0 = 6, so the number is divisible by 6. Therefore 1230000 is a Harshad (Niven) number in base 10.

The number of positive divisors of 1230000 can be computed from its prime factorization: (4+1) × (1+1) × (4+1) × (1+1) = 5 × 2 × 5 × 2 = 100. Thus 1230000 has 100 distinct divisors.

In summary, 1230000 is a highly factorable, even, composite number equal to 123 × 10,000, with a divisor structure that yields 100 divisors and a straightforward decimal representation as 1.23 million. See also: 123, 10,000, and 1,230,000.
