15 and 21 21 and 35
You need at least two numbers to find an LCM.
2 and 5 are both prime numbers. If you multiply them together, the answer is 10. 10 is the LCM of 2 and 5.
The least common multiple of 9 and 105 is 315.
The least common multiple of the numbers 105 and 90 is 630.
The LCM is 105.
The prime factors of 105 are 5, 3 and 7. So to work out which two numbers have 105 as an LCM, we just have to share these factors between the two numbers, and add in any duplicates we want. For instance: 5x3 = 15 3x7 = 21 So 15 and 21 have a LCM of 105. 7x5 = 35 3x5 = 15 So 35 and 15 have a LCM of 105. And so on.

Two or more numbers are needed to find their LCM but if you mean 7, 3 and 5 then it is 105
It is not possible to give a sensible answer to this question. The least common multiple (LCM) refers to a multiple that is COMMON to two or more numbers. You have only one number in each question!
You need at least two numbers to find an LCM.
For any two numbers, X and Y, LCM(X, Y) = X*Y/HCF(X, Y) So, LCM(525, 1155) = 525*1155/105 = 5775
The LCM of these numbers is 137235. LCM is Least Common Multiple.
2 and 5 are both prime numbers. If you multiply them together, the answer is 10. 10 is the LCM of 2 and 5.
The least common multiple of 9 and 105 is 315.
The LCM of the given three numbers is 105
The numbers could be 7 and 15 whose LCM is 105
