What is the smallest number which can be divided exactly by 22,44,55

1 answer

The smallest number that can be divided exactly by 22, 44, and 55 is the least common multiple of these numbers.

The prime factorization of the numbers are:
22 = 2 * 11
44 = 2^2 * 11
55 = 5 * 11

The least common multiple (LCM) of the numbers is the product of the highest power of each prime factor that appears in any of the numbers. So,

LCM(22, 44, 55) = 2^2 * 5 * 11 = 220

Therefore, the smallest number that can be divided exactly by 22, 44, and 55 is 220.
