The greatest common factor−5k2 20k − 30 is 
<h3>What is meant by the greatest common factor?</h3>
- The most common factor in mathematics is the highest number that may divide evenly into two other numbers.
- The largest factor that splits both numbers is the greatest common factor. List the prime factors of each integer before calculating the greatest common factor. One 2 and one 3 are shared by those aged 18 and 24. We multiply them to obtain the GCF. Therefore the GCF for 18 and 24 is 2 * 3 = 6.
- The biggest positive integer that divides evenly into all the numbers with no remainder is the greatest common factor (GCF, GCD, or HCF) of a collection of whole numbers.

Answer:
-6°C
-15°C
-1.5°C
Step-by-step explanation:
The computation is shown below:
in one hour the temperature falls by 3°C i.e.
= 0 - 3
= -3°C
In two hours
= 2 × - 3°C
= -6°C
In five hours
= 5 × -3°C
= -15°C
in half an hour
= 0.5 × -3°C
= -1.5°C
Answer:
5.625¢
Step-by-step explanation:
The amount of energy used by the chandelier is ...
5 × 0.075 kW × 1.5 h = 0.5625 kWh
At 10¢ per kWh, the cost will be ...
0.5625 kWh × 10¢/kWh = 5.625¢ . . . . cost of operation for 90 minutes
