Which is the smallest square number divisible by 4 9 and 13?
Hence the LCM of numbers 4,9,10 is180, where 180 is not a perfect number. Hence the number 900 is the smallest square number divisible by each number 4, 9, and 10.
What is the smallest square number which is divisible by?
L.C.M. of 8, 15 and 20 is 120. Here, prime factors 2, 3 and 5 have no pair. Therefore 120 must be multiplied by 2 x 3 x 5 to make it a perfect square. Hence, the smallest square number which is divisible by 8, 15 and 20 is 3600.
What is the smallest perfect square number divisible by 15 18 and 25?
Hence, 900 is the number which is divisible by 15,18 and 25 and is a perfect square.
What is the least square number?
From here, we obtain lcm(10,12,16)=24×3×5, hence the least square number required is 24×32×52=3600.
What least number must be added to 5607 to make it a perfect square?
Answer. Therefore, you must add 18 to 5607 to get the sum to be a perfect square.
What is the lowest common multiple of 4 9 and 10?
Answer: LCM of 4, 9, and 10 is 180.
Which is the smallest square number divisible by 4 9 and 10?
Hence, the smallest square number which is divisible by 4, 9 and 10 is 900.
IS 90 is a perfect square?
No because 90 cannot be written in the form of product of two equal numbers so it is not a perfect square. For e.g. 81 can be written in the form 9×9 hence it is a perfect square.
What is a perfect square called?
