Is 1380 an abundant number?

Here we will explain and calculate if 1380 is an abundant number and its abundance if applicable.

1380 is an abundant number if the sum of its proper divisors is greater than 1380.

The sum of its proper divisors is calculated as follows: 1 + 2 + 3 + 4 + 5 + 6 + 10 + 12 + 15 + 20 + 23 + 30 + 46 + 60 + 69 + 92 + 115 + 138 + 230 + 276 + 345 + 460 + 690 = 2652.

2652 is greater than 1380. Therefore, 1380 is an abundant number.

The abundance of 1380 is the sum of its proper divisors minus 1380. Thus, the abundance of 1380 is 2652 - 1380 = 1272
