1, 2, 4, 5, 10, 20.
100 & 140. The two numbers are: the mean ± half the range. Half the range is 40/2 = 20. So the two numbers are: 120 - 20 = 100 120 + 20 = 140
There are 20 numbers with at least one five in the numbers from one to 120.
The least common multiple of 20 , 40 , 30 = 120
which pair of numbers from 1 to 30 has the LCM OF 120
1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120.
It would be 20. After dividing both numbers by 20, you get 1 and 6. And these two numbers cannot be divided by any other numbers except by 1.
factors of 120: 2, 3, 5, 6, 10, 12, 20, 24, 40, 60 composite numbers of 120: 6, 10, 12, 20, 24, 40, 60
The LCM of the given numbers is 120
Some examples are: 1, 2, 3, 4, 5, 6, 10, 12, 20, 24, 30, 40, 60, 120.
The numbers 5, 30, and 20 are all factors of 30. Therefore, 30 is the smallest number into which all three of these numbers go evenly. Additionally, any multiple of 30, such as 60, 90, or 120, will also be divisible by 5, 30, and 20.
120 ÷ 6 = 20
The even square numbers between 20 and 120 are 36, 64, and 100. These correspond to the squares of the even integers 6, 8, and 10, respectively.
