The divisors of 101 are: 1, 101.
2,835 has 20 divisors.
120,000 has 70 proper divisors.
Since 11 is a prime number, its only divisors are 1 and itself.
The divisors of 21 are: 1, 3, 7, 21.
The divisors of 63 are: 1, 3, 7, 9, 21, 63.
The divisors of 147 are 1, 3, 7, 21, 49, 147.
The divisors of 42 are 1, 2, 3, 6, 7, 14, 21, 42.
The numbers that can go into both 21 and 100 are their common divisors. The divisors of 21 are 1, 3, 7, and 21, while the divisors of 100 are 1, 2, 4, 5, 10, 20, 25, 50, and 100. The only common divisor between the two is 1. Therefore, the only number that can go into both 21 and 100 is 1.
There are 8 divisors of 105 (viz: 1, 3, 5, 7, 15, 21, 35, 105)
The numbers that can go into both 21 and 99 are called common divisors. The common divisors of 21 and 99 are 1 and 3, as both numbers can be evenly divided by these values. The greatest common divisor (GCD) of 21 and 99 is 3.
The divisors of 126 are: 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, 126.
Eight. The odd divisors of 756 are: 1, 3, 7, 9, 21, 27, 63, 189.
1, 3, 7, 9, 21, 63.
The divisors of 42 are the numbers that can divide it without leaving a remainder. These divisors are 1, 2, 3, 6, 7, 14, 21, and 42. Therefore, 42 has a total of eight divisors.
