Why do we not use zero as a least common multiple of two numbers?
Asked by Wiki User
The concepts of GCF and LCM are restricted to positive integers. Zero can be considered a multiple of every number. That would make it the LCM of every set of positive integers, making the concept essentially meaningless.

How do you find least common denominators of odd numbers?
Asked by Wiki User
The same as any other set of numbers. Example 1/35 and 1/45
Factor them.
5 x 7 = 35
3 x 3 x 5 = 45
Combine the factors, eliminating duplicates.
3 x 3 x 5 x 7 = 315, the LCD

What is the greatest common factor of 28 42 and 63?
Asked by Wiki User
The GCF of 28, 42 and 63 is 7.
The GCF is 7.
What is the lowest common denominator of 10 and 14?
Asked by Wiki User
The relationship between 10 & 14 is a ratio of 10:14. This can be simplified to 5:7. If we now multiply the 10 by the 7 and the 14 by the 5 we end up with 70 each time. Therefore 70 is the LCM.
What is the greatest common factor of 34 51 102?
Asked by Wiki User
What is the gcf of 354 and 51 and 102
What is the LCM of 36ab and 4b?
