Well, Lets Look At Their Factors.
21: 1, 3, 7, 21
30: 1, 2, 3, 5, 6, 10, 15, 30
Since One Does Not Count For Least Common Factors, We go To The Next One They Both Have, 3!!
So, The Answer Is 3.
Answer: 40,000
Step-by-step explanation:
7/16 * 4/3 * 1/2 = 28/96 = 0.29
200 because 15 - 5 is 10 and 15+5 is 20. so 15 squared is 225 and 5 squared is 25 and 225-25 is 200
