Final answer:
To find the greatest number of balls that Brian can put into each bag while meeting the given conditions, find the greatest common divisor (GCD) of the three numbers: 245, 238, and 84. The GCD is 7, so the greatest number of balls that Brian can put into each bag is 7.
Step-by-step explanation:
In order to find the greatest number of balls that Brian can put into each bag while meeting the given conditions, we need to find the greatest common divisor (GCD) of the three numbers: 245, 238, and 84.
First, find the GCD of 245 and 238:
Divide 245 by 238 to get a quotient of 1 and a remainder of 7.
Divide 238 by 7 to get a quotient of 34 and a remainder of 0.
Therefore, the GCD of 245 and 238 is 7. Now find the GCD of 7 and 84:
Divide 84 by 7 to get a quotient of 12 and a remainder of 0.
Therefore, the GCD of 7 and 84 is 7. So, the greatest number of balls that Brian can put into each bag is 7.
