1, 3 and 9 will go into both numbers evenly
The number that is a factor of 72 and a multiple of 8 is 8. A factor of a number divides that number evenly without leaving a remainder, and 8 divides 72 evenly. Additionally, a multiple of a number is the result of multiplying that number by an integer, and 8 multiplied by 9 equals 72. Therefore, 8 is both a factor of 72 and a multiple of 8.
The greatest common divisor (GCD) of 72 and 56 is 8, which is the largest number that can evenly divide both. Additionally, the common divisors of 72 and 56 include 1, 2, 4, and 8. Therefore, the numbers that go into both 72 and 56 are 1, 2, 4, and 8.
