Answer:
30
Solution:
A number and 42 has a GCF of 6 and LCM
the number? How many times of 210. What is
ll you multiply the GCF to get this number?
Solution:
30 2 42
15 3 21
5 7
GCF = 2 x 3 = 6
LCM = 2 x 3 x 7 x n = 210
= 210 42 x n
= 210/42 n
= 5 n
Therefore, the missing number is 30. You
will have to multiply the GCF 6 by 5 to get 30.
