this question is the same as asking what is LCM of 6 and 16
so using prime factorzation
6=3*2
16=2*2*2*2
so the least common multiple will be
3*2*2*2*2=48
the final answer is at 00:48 A.M

is the same as asking fot the GCF(84,72)
84=2*2*3*7
72=2*2*2*3*3
thus the GCF is 2*2*3=12
she will have 84/12=7 whistles and 72/12=6 bouncy ball
7 a)
GCF(40,52)
40=2*2*2*5
52=2*2*13
the GCF is 2*2=4
7 b)
LCM(40,52)
40=2*2*2*5
52=2*2*13
the LCM is 2*2*2*5*13=520
