42, it has to be an even number because of the 2, so just methodically go through the 7 times table, eg 14, 28, 42
The LCM is 105.
The LCM of the given three numbers is 14
The LCM of the given three numbers is 315
5 and 7 8 and 17 22 and 25
The two numbers are coprime so the LCM is 7*235 = 1645
The LCM of the given three numbers is 56
The LCM of 7 and 9 is 63.
Same as finding the LCM of 6, 5, 7: 2*3*5*7 = 210
Unless the other number is a multiple of 7, the LCM will be the product of the two. If the other number is a multiple of 7, the LCM will be the other number.
105 because if you divide 21 and 15 by three you get 7 and 5 and when you multiply 7, 5, and 3 together you get 105.
You need at least two numbers to find an LCM.
The Least Common Multiple (LCM) of (6,7,8) is 168.We can calculate the LCM of three numbers by splitting it up into two LCM calculations. First, we will find the LCM of any two numbers, and then find the LCM of that number, and the last number.To start, let's find the LCM of 6 and 8. The only common factors of 6 and 8 are 1 and 2, so we will multiply those two numbers to get 2, and divide the 6x8 by 2, getting 24.Now we need to find LCM(24, 7). The only common factor of 24 and 7 is 1, so the LCM of 6, 7, and 8 is (24x7)/1=168.
