7520

7520 is a positive integer that appears in usual decimal notation as a four-digit even number. It is an integer with several notable arithmetic properties that place it within standard number-theory discussions of composites and divisibility.

Its prime factorization is 2^5 × 5 × 47, giving it 24 positive divisors. The sum of all divisors equals 18144, so the sum of proper divisors is 10624, which is greater than 7520. Therefore the number is abundant, not perfect or deficient. It is also divisible by 32 and by 16, reflecting the high power of 2 in its factorization. The greatest common divisor with 1000 is 40, illustrating its overlap with base-10 factors.

In other bases, 7520 has the representations: binary 1110101100000, hexadecimal 0x1D60, and octal 16540. These can be useful in computing contexts where different numeral systems are used to express the same value.

Other numeric properties include its parity (even) and its digits summing to 14, which means 7520 is not a Harshad (Niven) number in base 10, since 7520 is not divisible by 14. As a four-digit, composite number with a clear factor structure, 7520 often appears as an example in elementary number theory and digital representations without carrying any associated historical or cultural significance.
