What is greatest common factor of 45 and 75?
These numbers are divided by 5 without remainder, so their common factor must be divided by 5 without remainder aswell. Let's start from 45 stepping over 5 and skipping any unmatching result: not 45, not 40, not 35, not 20 (since none of 45 and 70 divide these without reminder), but it's 15 (which gives us 45/15 = 3 and 70/15 = 5, here both results are round numbers, which gives us 15 as the answer).
What is the least common multiple of 35 50 and 7?
35 is not the LCM of 3 and 5, 15 is. LCM means Lowest Common Factor. To find the LCM of 3 and 15 you have to list the multiples: 3, 6, 9, 12, 15, 18, 21 etc. 5, 10, 15, 20, 25, etc. The LCM is the least common number in both the lists, which is 15.
Find two pairs of numbers with 105 as LCM?
15 and 21 21 and 35
What do 3 and 5 both go into?
3 and 5 both go into multiples of 15, as both numbers are factors of 15. In mathematical terms, 15 is a multiple of both 3 and 5 because it can be evenly divided by both numbers without leaving a remainder.
What are the two pairs of numbers that have 11 as their LCM?
The LCM of 2 and 3 is 6. The LCM of 5 and 7 is 35. The LCM of 11 and 19 is 209.
What number divide into 15 and 35 with no remainder?
5
Divide 35 into 120?
3 with a remainder of 15 or 3.4286
What are the are 3 numbers that divide into 113 with a remainder of 8?
If there is a remainder of 8 when they divide into 113, then they must be factors of 113 - 8 = 105, but not factors of 113, and greater than 8: The factors of 105 are: 1, 3, 5, 7, 15, 21, 35, 105 The factors of 113 are: 1, 113 Thus the 3 numbers which divide 113 with a remainder of 8 are 15, 21, 35, 105 (oops, there are 4 numbers which satisfy the criteria - I never could count...)
What number do you divide by ten and get a remainder of 5?
All numbers of that kind: 5, 15, 25, 35, 45, 55, 65... 105, 115... and so on
Why is 7 not the GCF of 15 30 and 35?
7 is not the greatest common factor (GCF) of 15, 30, and 35 because 7 does not evenly divide into all three numbers. The GCF is the largest number that can divide all three numbers without leaving a remainder, and in this case, the GCF is actually 5 since 5 divides evenly into all three numbers.
Why is the factor of 105 is1357152135105?
The factors of 105 are 1, 3, 5, 7, 15, 21, 35, 105. They are the only numbers that will divide evenly with no remainder into 105.
What numbers are not multiples of 35?
All numbers that leave a remainder when divided by 35.
How do you change improper fractions to whole or mixed numbers?
Simply enough, divide. Example 1: What is 105/7? Well, since 7 goes into 10 once, remainder 3, and into 35 five times, the answer is 15. Example 2: What is 150/13? We divide 15/13 and get 1, remainder 2. "Bring down" the 2, and we divide 20/13 and get 1, remainder 7. So the answer is 11 7/13.
What are the factors of 35 20 and 15?
A factor of a number is any number which the original number can divide into evenly. That is to say, can divide into without leaving a remainder, decimal or fraction. The factors of 15 are: 1, 3, 5 and 15 The factors of 20 are: 1, 2, 4, 5, 10 and 20. The factors of 35 are: 1, 5, 7 and 35.
What is 750 divided by 21 with remainder?
35.7143
How do you find the ratio of 35 and 15?
Divide both numbers by 5 changes the ratio to: 7 and 3
What can you divide 105 into?
105 can be divided evenly by 1, 3, 5, 7, 15, 21, 35, and 105. These are all the factors of 105, meaning they divide into 105 without leaving a remainder. Additionally, 105 can be divided by other numbers that are not factors, but those divisions will result in remainders.
