A018373 - OEIS

This site is supported by donations to The OEIS Foundation.

Please make a donation to keep the OEIS running. We are now in our 55th year. In the past year we added 12000 new sequences and reached 8000 citations (which often say "discovered thanks to the OEIS"). We need to raise money to hire someone to manage submissions, which would reduce the load on our editors and speed up editing.

	OFFSET	`1,2`
	COMMENTS	`This number has six divisors that add up to 504, and 504 - 284 = 220, so 284 is a deficient number. In turn, 220 is an abundant number with twelve divisors (see A018339) which also add up to 504, and 504 - 220 = 284. - Alonso del Arte, Oct 22 2017`
