3 and 1 will go into both number evenly leaving no remainders.
Just 1 and 3.
The numbers that go into both 21 and 70 evenly are their common factors. The greatest common divisor (GCD) of 21 and 70 is 7, which means 7 is the largest number that divides both evenly. The factors of 21 are 1, 3, 7, and 21, while the factors of 70 are 1, 2, 5, 7, 10, 14, 35, and 70. Thus, the common factors are 1 and 7.
If the sum of the digits equals 3, the number is evenly divisible by 3. 2 + 0 + 1 = 3, so 201 is evenly divisible by 3. 1, 3, 67, 201
It can be divided by 3 and the answer is 41
