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.
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.
Same as finding the LCM of 6, 5, 7: 2*3*5*7 = 210
You need at least two numbers to find an LCM.
The LCM of 7 and 9 is 63.
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.
