	OFFSET	`1,2`
	COMMENT	`a(n) = A002182(n) / A152047(n). [From Klaus Brockhaus (klaus-brockhaus(AT)t-online.de), Nov 27 2008]`
	EXAMPLE	`a(9) = 10 because the ninth highly composite number is 60 and 10 is the smallest divisor of 60 >= sqrt(60). (Although 8 >= sqrt(60), 8 does not qualify because it is not a divisor of 60.)`
