Original: The dozen is convenient because its multiples and divisors are convenient : 12 = 2 & times ; 2 & times ; 3 , 3 & times ; 4 = 2 & times ; 6 , 60 = 12 & times ; 5 , 360 = 12 & times ; 30 .
Simplified: The dozen is convenient because its multipliers and multiples are convenient : 12 = 3 & times ; 2 & times ; 2 , and 360 = 30 & times ; 12 .
