2500000

2500000, written out as two million five hundred thousand, is the positive integer that follows 2,499,999 and precedes 2,500,001. In decimal it ends with five zeros, reflecting its factorization as 2^5 × 5^7 and equivalently as 25 × 100,000. It is an even and composite number.

Mathematical properties include its prime factorization, 2^5 × 5^7, which shows it is a multiple of both 2^5 and 5^7 and, more importantly, a multiple of 10^5. The number of positive divisors is (5+1) × (7+1) = 48. Euler’s totient function for this number is φ(2^5 × 5^7) = 2^4 × (2−1) × 5^6 × (5−1) = 1,000,000.

Other representations and simple calculations related to 2,500,000 include its scientific notation form (2.5 × 10^6). It is approximately 2.38 mebibytes (MiB) in bytes, since 2,500,000 bytes divided by 1,048,576 is about 2.38. In time terms, 2,500,000 seconds is roughly 28.9 days. The number thus appears in various counting, measurement, and computational contexts as a round, milestone value.
