120000000

120,000,000, or one hundred twenty million, is a natural number that follows 119,999,999 and precedes 120,000,001. In scientific notation it is written as 1.2 × 10^8.

Mathematically, it factors as 2^9 × 3 × 5^7. Its prime factorization shows it is a composite number. The sum of its digits is 3, so the number is divisible by 3 but not by 9. It is even and ends with zero, so it is divisible by 2 and 5; more broadly, it is divisible by 1000 and by 512 through its 2^9 and 5^7 factors.

120,000,000 has 160 positive divisors, calculated by multiplying (9+1)(1+1)(7+1) = 10 × 2 × 8.

In computing and data measures, 120,000,000 bytes is approximately 114.4 mebibytes (MiB), or about 120 megabytes (MB) in decimal terms. This makes it a frequently cited example of a large, round-sized quantity in discussions of memory, data storage, and bandwidth.

As a decimal with a fixed pattern (12 followed by seven zeros), 120,000,000 is sometimes used in arithmetic demonstrations and benchmark contexts to illustrate factors, divisibility, and scaling properties of large integers.
