НОК(28,55,80)

To find the least common multiple (LCM) of 28, 55, and 80, you can follow these steps:

Step 1: Prime factorize each number:

28 = 2^2 * 7 55 = 5 * 11 80 = 2^4 * 5

Step 2: Take the highest power of each prime factor:

The prime factorization of the LCM will include 2^4, 5^1, 7^1, and 11^1.

Step 3: Multiply the highest powers together:

2^4 * 5^1 * 7^1 * 11^1 = 2^4 * 5 * 7 * 11 = 6160

Therefore, the least common multiple (LCM) of 28, 55, and 80 is 6160.
