Answer 1

Least Common Multiple.

60

2 = 30
5 = 12
6 = 10
9 = 6.666667

60 is NOT the least common multiple, because 9 cannot get into it with a whole number.

Answer 2

45

2 = 22.5

45 is NOT the least common multiple, because 2 cannot get into it with a whole number.

Answer 3

2=2
5=5
6=2x3
9=3x3
lcm=2x5x3x3=90

Answer 4

2 = 45
5 = 18
6 = 15
