The prime number that is greater than 20 but less than 29 is 23.
The divisors of 40 are: 1, 2, 4, 5, 8, 10, 20, 40.
23 and 29 are the two prime numbers greater than 20 but less than 30.
Because the sum of its proper divisors is greater than 20.
2,835 has 20 divisors.
No, 2 Kg (Kilograms) is greater than 20g (grams).
No; 20 is an abundant number. S = {1, 2, 4, 5, 10} is the set of all positive divisors of 20, excluding itself. The sum of these divisors = 1+2+4+5+10=22 which is greater than 20. Therefore 20 is an abundant number, not a deficient number. When the sum exceeds the number, the number is abundant. When the sum equals the number, the number is perfect. When the sum is less than the number, the number is deficient.
