WebbWhat is the smallest number with 11 factors? We desire this product to be 11, which only has divisors 1 and 11, hence we can only have one (aj+1)=11 (aj=10) and the rest must be zero. Therefore our number can be any prime number raised to the 10th power, for example, 2^10=1024, which is the smallest such number. WebbThe smallest of these numbers is 5 1 * 3 2 * 2 2 = 180 The question is "Find the smallest number that has exactly 18 factors." Hence the answer is 180. Choice C is the correct answer. « First 8 9 10 11 12 » Last CAT Online Coaching CAT Number Systems questions Videos On YouTube 1.
Webb29 juni 2006 · Hello. Quite a while ago, I was asked to find the smallest positive integer with 12 positive even divisors and 6 positive odd divisors. After trying for a while and not finding the answer, I read that the smallest number with 6 odd divisors is 3^2(5), and to get additionally 12 even, we must multiply by 2^2. Webb17 apr. 2024 · Since 12=22⋅3 the smallest answers involving the fewest prime numbers are: 211=2048. 25⋅3=96. 23⋅32=72. 22⋅3⋅5=60. But you can get larger answers by substituting other primes for 2,3,5 in the above expressions. By the way the twelve factors of 60 are: 1,2,3,4,5,6,10,12,15,20,30, and 60.
