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 315
The LCM of the given three numbers is 14
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.
You need at least two numbers to find an LCM.
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.
The LCM of 7 and 9 is 63.
