90
Only 80.
91, 93, 95, 97, 99, 101, 103, 105, 107, 109
Including 101: 101, 103, 107, 109, 113, 127, 131, 137, 139, 149. There are 10.
There is not a least common multiple of a single number, such as 10, because there cannot be a least common multiple without two or more numbers to compare. Common multiples are multiples that the numbers being compared have in common. The least common multiple is the smallest multiple that all the numbers being compared have in common.Examples:The least common multiple of 8 and 10 is 40.The least common multiple of 10 and 35 is 70.The least common multiple of 10 and 43 is 430.The least common multiple of 3, 10, and 66 is 330.You need to provide two or more positive integer numbers to properly answer this.
90
It is: 80
To be a multiple of 4, 10 and 20 the number must be a multiple of their lowest common multiple. lcm(4, 10, 20) = 20 What is required is a multiple of 20 between 61 and 107. The numbers 80 and 100 both satisfy the problem of being between 61 and 107 and being a multiple of 4, 10 and 20.
All numbers that are multiples of all 2, 8 & 10 are multiples of their lowest common multiple which is 40.The multiples of 40 are 40, 80, 120, 160, ... of which only 80 is between 61 and 107.

80 adn 100
The number is 90.
98
It is: 80 and 100
80 and 100 are the only numbers between 67 and 113 that are multiples of 4,5 and 10.
