1010101012

1010101012 is a numeric string that can denote different things depending on the context. In standard decimal notation, it represents the integer 1,010,101,012. The digits show a pattern of alternating 1s and 0s for the first nine positions, followed by a final 2.

As a decimal integer, 1,010,101,012 is even and therefore divisible by 2. The last two digits are 12, which implies divisibility by 4, but the last three digits are 012, which means it is not divisible by 8. The digit sum is 7, so it is not divisible by 3. Its prime factorization begins with 2^2 × 252,525,253, meaning 1,010,101,012 = 4 × 252,525,253. The factor 252,525,253 is odd; a full factorization would require additional testing with larger primes.

Alternative interpretation: if the sequence of bits were read as a binary number, written as 101010101_2, its value would be 341 in decimal. The literal string 1010101012 (without a subscript) is typically read as decimal; including a subscript would indicate base 2.

Applications and context: the pattern of alternating digits is sometimes used in examples to illustrate digit parity, base conversions, or test data in computing. The specific value 1,010,101,012 is a concrete instance of a moderately large even integer with a straightforward factor of 4.
