The factors of 15 are:
1, 3, 5, 15
The factors of 180 are:
1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90, 180
prime factors of 180:(180) = 2 * (90)(90) = 2 * (45)(45) = 3 * (15)(15) = 3 * 5prime factors of 180 are: 2*2*3*3*5
The common factors of 180 and 225 are 1, 3, 5, 9, 15 and 45.
The factors of 135 are: 1, 3, 5, 9, 15, 27, 45, 135 The factors of 180 are: 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90, 180
First of all add all common factors. In par. (2x) + 15 + (2x) = 180 4x + 15 = 180 Divide 4x and 180 by 4. (4x/4) + 15 = (180/4) x + 15 = 45 Then subtract 15 to 15 and 45. x + (15-15) = (45-15) x = 30 Answer is X = 30.
The factors of 180 are: 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90, 180.
The factors of 180 are 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90, 180. For them to be common, they need to be compared to another set of factors.
Factors of 90 will be factors of 180.
The factors of 150 are: 1, 2, 3, 5, 6, 10, 15, 25, 30, 50, 75, 150 The factors of 180 are: 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90, 180
15% of 180= 15% * 180= 0.15 * 180= 27
15% off of 180 = 15315% off of 180= 15% discount applied to 180= 180 - (15% * 180)= 180 - (0.15 * 180)= 180 - 27= 153
Factors of 90 are 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, and 90 Factors of 180 are 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90, and 180 The factors of 90 and 180 not common to both numbers are 4, 12, 20, 36, 60, and 180.
The LCM of 15, 18, and 20 is 180. To arrive at an LCM we need to factorize the candidate numbers, and then ensure that each factor is included in the factors which will create the LCM The prime factors of 20 are 2, 2 and 5 so all of those must be in the LCM The factors of 15 are 3 and 5. As we have a 5 already we only need to add the 3 to the list. Now we have 2, 2, 3 and 5 The factors of 18 are 2, 3 and 3. As we have a 2 and one 3 already, we need to add the second three to the list..... this gives us 2, 2, 3, 3 and 5 as the factors that will give us the LCM Multiplying these together we get 180 180 / 20 = 9 180 / 15 = 12 180 / 18 = 10 As 9, 12 and 10 don't share any factors we can see that 180 is indeed the LCM of the three numbers we were given.
