How can you draw a flow chart to find prime numbers?
The first action sequence in the flow chart is to remove all multiples of 2 from numbers greater than 2. The next sequence removes removes all multiples of 3 from all numbers greater than 3. The third sequence removes all multiples of 5 from the remaining numbers greater than 5. The fourth sequence removes all multiples of 7 from the remaining numbers greater than 7. Additional sequences are added as needed to remove multiples of as many primes as desired in ascending order.
What are all multiples of 6 that are greater than 29 and are also less than 50?
30, 36, 42, 48
What multiples of 24 add up to 19?
There aren't any. All multiples of 24 are greater than 19. If you mean factors, you can use 12, 6 and 1 or 8, 6, 3, 2.
Is a 3-digit number all the digits are different the first and second digits are multiples of 3 the first digit is greater than the second digit?
Not necessarily. Consider 444. The digits are not different. The first and second digits are not multiples of 3 The first digit is not greater than the second digit. In spite of all that, 444 is a 3-digit number
Which is greater LCM or GCF. Why?
The GCF and LCM of 10 and 10 is 10. But apart from that special circumstance, the LCM will never be less than the GCF. Apart from a number itself, all of its factors are smaller than it. Apart from a number itself, all of its multiples are larger than it. You can't have a GCF that is greater than the smaller number, and you can't have an LCM that is less than the larger one. Factors go into numbers, numbers go into multiples.
