We can make this an equation, lets start with how much money he has. Since he bought the motorbike he lost 2,000, then sold it and received 2,500. The 2,000 cancels out but he still has 500. Now that he bought it for 2,200 we subtract 2,200 from 500 and get -1,700. Then finally, he sold it for 2,000 so we add that to -1,700 and get 300. His total profit was $300.
-2,000 + 2,500 = 500
500 - 2,200 = -1,700
-1,700 + 2,000 = 300
Answer:
GCF = 12
for the values 144, 180, 240, 300
Solution by Factorization:
The factors of 144 are: 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 36, 48, 72, 144
The factors of 180 are: 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90, 180
The factors of 240 are: 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 40, 48, 60, 80, 120, 240
The factors of 300 are: 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 25, 30, 50, 60, 75, 100, 150, 300
Then the greatest common factor is 12.
