1, 2 and 4
The numbers that go into both 14 and 20 are called common divisors. The common divisors of 14 are 1, 2, 7, and 14, while the common divisors of 20 are 1, 2, 4, 5, 10, and 20. The only common divisors between the two numbers are 1 and 2. Therefore, 1 and 2 are the numbers that go into both 14 and 20.
All numbers have divisors. Some numbers have some of the same divisors as other numbers. These are called common divisors. 3 is a divisor of 9. 3 is a divisor of 12. 3 is a common divisor of 9 and 12.
The numbers that go into both 12 and 30 are their common divisors. The divisors of 12 are 1, 2, 3, 4, 6, and 12, while the divisors of 30 are 1, 2, 3, 5, 6, 10, 15, and 30. The common divisors of 12 and 30 are therefore 1, 2, 3, and 6. The greatest common divisor (GCD) is 6.
The numbers that go into both 20 and 16 are their common divisors. The divisors of 20 are 1, 2, 4, 5, 10, and 20, while the divisors of 16 are 1, 2, 4, 8, and 16. The common divisors are 1, 2, and 4. Therefore, the numbers that go into both 20 and 16 are 1, 2, and 4.
The numbers that go into both 12 and 9 are their common divisors. The common divisors of 12 are 1, 2, 3, 4, 6, and 12, while the common divisors of 9 are 1, 3, and 9. The only common divisor between 12 and 9 is 1 and 3. Thus, 1 and 3 are the numbers that go into both 12 and 9.
60?
The numbers that can go into both 20 and 100 are their common divisors. The common divisors of 20 and 100 are 1, 2, 4, 5, 10, and 20. The greatest common divisor (GCD) is 20, meaning 20 is the largest number that divides both without leaving a remainder.
The numbers that can go into both 12 and 32 are called common divisors. The common divisors of 12 are 1, 2, 3, 4, 6, and 12, while the common divisors of 32 are 1, 2, 4, 8, 16, and 32. The only numbers that are common to both lists are 1, 2, and 4. Thus, 1, 2, and 4 can go into both 12 and 32.
The numbers that go into both 132 and 36 are their common divisors. The greatest common divisor (GCD) of 132 and 36 is 12. The common divisors are 1, 2, 3, 4, 6, and 12.
The numbers that can go into both 12 and 30 are their common divisors. The common divisors of 12 and 30 are 1, 2, 3, and 6. The greatest common divisor (GCD) is 6. Thus, 1, 2, 3, and 6 can evenly divide both 12 and 30.
12 divisors: 1 2 4 5 10 11 20 22 44 55 110 220.
The numbers that go into both 46 and 60 are their common divisors. The divisors of 46 are 1, 2, 23, and 46, while the divisors of 60 are 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, and 60. The common divisors of 46 and 60 are 1 and 2. Therefore, the numbers that go into both 46 and 60 are 1 and 2.
