Final answer:
To determine if 4 is a factor of 146, we need to check if 4 divides evenly into 146. The last two digits of 146 are 46, which is not a multiple of 4.
Step-by-step explanation:
To determine if 4 is a factor of 146, we need to check if 4 divides evenly into 146. If 4 divides evenly into 146, then 146 is a multiple of 4. To check if 4 divides evenly into a number, we can use the divisibility rule for 4. If the last two digits of the number form a multiple of 4, then the entire number is divisible by 4. The last two digits of 146 are 46, which is not a multiple of 4. Therefore, 4 is not a factor of 146.
