EXPLANATION
The prime factorization of the two numbers are
and
To find the least common multiple , we collect the factors with the powers and multiply them out.
The highest power of 2 is
The highest power of 3 is
The highest power of 5 is
and the highest power of 7 is
Therefore
Answer:
15, 21, 35, 105
Step-by-step explanation:
A composite number is a positive integer that has more than two different factors. For example, composite number include 4, 6, 8, 9, 10, 12, 14, 15, 16, 18...etc.
So, if we multiply 3x5x7=105
All the factors of 105 are 1, 3, 5, 7, 15, 21, 35, 105. So we just need to figure out the factors that are composite which are
15, 21, 35, 105
Answer:
268.67 pages per hour
She read the whole book is 1.79 hours.
Step-by-step explanation:
Shryia read for 1.5 hours 403 pages of a 481 page book. Her rate is the number of pages she read divided by the time it took her.
403 / 1.5 = 268.67 pages per 1 hour.
To find how long it took her to read the whole book, divide 481 by her rate.
481 / 268.67 = 1.79
She read the whole book is 1.79 hours.
