Answer:
4
Explanation:
1*12=12 1*20=20
2*6=12 2*10=20
3*4=12 4*5=20
both have a similar multiple of 4, so k must be 4.
Factors of 12 : 1, 2, 3, 4, 6, 12
Factors of 20: 1, 2, 4, 5, 10, 20
In both lists of factors, 4 is in common. Therefore, the value of K is 4 because it can divide into both 12 and 20 without a remainder. 2 is also another possible value of K.
