Are 1184 and 1210 amicable numbers?
1184 = 1+2+5+10+11+22+55+110+121+242+605, the sum of the divisors of 1210. … In researching this puzzle, it turns out that numbers are amicable if there are two that sum to each other’s proper divisors; they are social numbers if they sum not as a pair, but as a chain, like: 12496, 14288, 15472, 14536, 14264.
Why is three the perfect number?

What is the weirdest number?
Examples. The smallest weird number is 70. Its proper divisors are 1, 2, 5, 7, 10, 14, and 35; these sum to 74, but no subset of these sums to 70. The number 12, for example, is abundant but not weird, because the proper divisors of 12 are 1, 2, 3, 4, and 6, which sum to 16; but 2 + 4 + 6 = 12.

How do you find an amicable number in Python?
Python Program to Check If Two Numbers are Amicable NumbersTake in both the integers and store it in separate variables.Find the sum of the proper divisors of both the numbers.Check if the sum of the proper divisors is equal to the opposite numbers.If they are equal, they are amicable numbers.Print the final result.Exit.
How do you prove that 496 is a perfect number?
Yes, 496 is a perfect number, that is to day 496 equals the sum of its proper positive divisors, i.e., the sum of its divisors excluding 496 itself. Indeed, 496 = 1 + 2 + 4 + 8 + 16 + 31 + 62 + 124 + 248.
How do you find an amicable number?

Why is 8 a perfect number?
In number theory, a perfect number is a positive integer that is equal to the sum of its positive divisors, excluding the number itself. … The sum of divisors of a number, excluding the number itself, is called its aliquot sum, so a perfect number is one that is equal to its aliquot sum.
Why is 28 a perfect number?
A number is perfect if all of its factors, including 1 but excluding itself, perfectly add up to the number you began with. 6, for example, is perfect, because its factors — 3, 2, and 1 — all sum up to 6. 28 is perfect too: 14, 7, 4, 2, and 1 add up to 28.
