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.
The least common multiple of the numbers 6 and 10 is 30.
The Least Common Multiple (LCM) of 10 and 20 is 20. Since 20 is a multiple of 10, it is automatically the LCM of the set.20 is.
The greatest common multiple of 10 and 18 is infinite.However, I suspect you want either:the greatest common factor of 10 and 18 which is the largest number which divides both 10 and 18 and is 2; orthe lowest common multiple of 10 and 18 which is smallest number into which both 10 and 18 divide (ie the smallest number which is a multiple of both 10 and 18) and is 90

The highest common multiple is an infinite number.
The least common multiple (LCM) refers to a multiple that is COMMON to two or more numbers. You have only one number in the question! The least multiple of a number is itself.
The only such number between 55 and 101 is 80.
The Least Common Multiple (LCM) of (3,7,10) is 210
It is 70
