Women's Relaxed T-Shirt - Purrfect Numbers, Imperfect Us? JWST To prevent scratch marksDesign Backstory Not Ed Sheerans purring out his Perfect lovesong but official eternal perfect numbers. These are numbers equal to the sum of their proper divisors, excluding themselves (eg 6 = 1+2+3, 28 = 1+2+4+7+14). Euclid found a general rule to find a perfect number for primes.
