Yes, 2 is a factor of 72. To determine if a number is a factor of another, we divide the second number by the first and check if the result is a whole number.
In this case, if we divide 72 by 2, we get:
72 ÷ 2 = 36
Since 36 is a whole number, it confirms that 2 is indeed a factor of 72. Additionally, factors of a number are those integers that can multiply together to produce that number. Since 2 x 36 equals 72, we can see clearly that 2 is a factor of 72.
