Firstly, 2, -2, and -1, 1 all go into -120 and -2 (both are even). However, 2, -2 are the only ones that are proper (non-1 values).
2 and 3.
60
How about: -2 times -60 = 120 as an example
2 and 60 will divide evenly into 120.
How about: 2*120 = 240
100 & 140. The two numbers are: the mean ± half the range. Half the range is 40/2 = 20. So the two numbers are: 120 - 20 = 100 120 + 20 = 140
16 x 15 / 2 ie 120
10x12 1 x 120 2 x 60 3 x 40
1, 2, 4, 5, 10, 20.
1, 2, 3 and 6 will go into both numbers
120 = 2*2*2*3*5, so there is 5 prime numbers, no 2 prime numbers
It is a pattern. Go up two numbers, go down two numbers.
