Question

До кіоску з квітами завезли троянди. Якщо розкласти їх у вази по 15 або по 21 штук, то в обох випадках зайвих квітів не залишиться. Яка найменша кількість квітів могла бути завезена?​

Answer 1

Ответ:

ну хз я посмотрел у брата

Answer 2

ХЗ если будет правилным

НСК(15;21)=7×5×3=105

Answer 3

To find the minimum number of flowers that could have been delivered to the flower kiosk, we need to find the least common multiple (LCM) of 15 and 21. The LCM is the smallest number that is divisible by both 15 and 21 without leaving any remainder.

The LCM of 15 and 21 is 105. Therefore, the minimum number of flowers that could have been delivered is 105.

Let's verify this using the search results.

According to the search results, the LCM of two numbers can be found by using the prime factorization method or by using the division method. Let's use the division method to find the LCM of 15 and 21.

Division Method to Find LCM:

1. Write down the two numbers: 15 and 21. 2. Find the prime factors of each number: - Prime factors of 15: 3, 5. - Prime factors of 21: 3, 7. 3. Multiply the highest power of each prime factor: - Highest power of 3: 3. - Highest power of 5: 5. - Highest power of 7: 7. 4. Multiply the highest powers of each prime factor together: - LCM = 3 * 5 * 7 = 105.

Therefore, the minimum number of flowers that could have been delivered is 105.
