which pair of numbers from 1 to 30 has the LCM OF 120
Since 120 is a multiple of itself, all you need to do is pair it with any other factor of 120. 120 and 60 have an LCM of 120.
120 and 4
10 and 12
30 and 40
240
This doesn't work. The LCM of a pair of numbers has to be equal to or larger than the largest number of the pair. If one of the numbers is 60, the other is 120. 60 and 120 have a GCF of 60, not an LCM.
HCF is the highest common factor of two or more numbers. One such pair which has 60 as their HCF can be: 120 and 180.
The numbers are 38, 40 and 42.
4/120, 8/60
We have the numbers x and y. x+y=120 x-y=50 2x=170 x=85 y=35
It is impossible to answer this question because of insufficient information: The question does not state how many numbers are concerned. The LCM and GCF of a pair of numbers is NOT sufficient to identify them. For example, (3, 120), (15, 24) satisfy the requirements and there is no way to determine which of them is appropriate.
