The least common factor - the smallest number which divides them all - is 1.
The number 30 is the smallest whole number divisible by both 10 and 6.
It is: 1410
It is: 36
The highest common factor of two numbers is always equal to the smallest number if that number is a factor of the larger number. This is the case here. Since 6 is a factor of 36, 6 is the highest common factor of 6 and 36.
The least common factor of any set of integers is 1.
10 is a multiple of 6 and a factor of 60 :)
