What is the smallest number you can make using the digits 2519?
The answer is -9999 as the value of -9999 is less than the value of 1000.
What is the smallest number that can be divisible by 15?
If a number is to be divisible by 15, it must end with 5 and the sum of its digits must be a multiple of 3. The first and the last numbers must both be 5, so the sum must be 12 (next multiple of 3). So we’ll just use the middle digit as 2, and the rest can be 0. Smallest: 5,002,005 Using the same logic, we can write 5999995 (sums to 55).
What is the smallest 5-digit number divisible by 8 and 300?
– Now, the LCM of 300 and 8 is 600. So the smallest 5 digit number divisible by the given numbers is 17*600 = 10200. Originally Answered: What will be the smallest 5 digit number which is divisible by 8,15,20,25?
What is the number that is divisible by 12 15 and 20?
15=3*5. 20=2*2*5. LCM=2*2*3*5=60. So 60 is the number that is divisible by 12, 15 and 20. What is the least perfect square number which is divisible by each of numbers 8, 12, 15, and 20? First let us factorise the given numbers and see their powers. 2^4 x 3^2 x 5^2 is sufficient and least number which will satisfy all conditions.
What is the smallest 4-digit number divided by 45 30 and 12?
The smallest number dividable by 45, 30 and 12 is 180. Thus the smallest 4-digit number has to be a product of 180 and n (where n is a natural number). The smallest 4-digit number is 1000 (if 0000, 0001, 0010 etc. is not accepted).
