The LCM of 5 and 8 is 40. I don't know the listing method.
if you use "ladder" method you'll see 5 goes into 6,5,and 8. When you divide 5 into 6,5,8 with a remainder of 1,1,and3. Then multiply 5,1,1,and3 and you get 15 as the L.C.M of 6,5,8.
3 x 5 = 15 2 x 2 x 2 x 2 x 2 = 32 2 x 2 x 2 x 2 x 2 x 3 x 5 = 480, the LCM
2 x 2 x 5 = 20 The LCM is 20wy.
Two or more numbers are normally needed to find the LCM
First you write down the numbers you are given and put them on an upside-down long division symbol. Divide the two together until you get to where you cannot divide any longer. Take the right side and bottom numbers and multiply them. This should be your LCM. If you cannot divide them at the first division, use the Listing Method, which is listing some of the multiples of that number and see which one is the smallest same number. Hope this helped.
4, 8, 12, 16, 20, 245, 10, 15, 20, 25The LCM is 20.
2 x 25Combine the factors.2 x 2 x 5 = 20, the LCM
5 or 1 5 would be the greatest common factor (GCF) but the LCM (Least Common Multiple) is found by either listing factors of both numbers, or by prime factorization. The prime factorization method: 30 = 2*3*5 35 = 5*7 So the LCM = 2*3*5*7 = 210 Note that 210/30 = 7 and 210/35 = 6 so both numbers, 30 and 35 are factors of 210. The listing method: 30,60,90,120,150,180,210 35,70,105,140,175,210 So 210 is the first (least) number that is a multiple of 30 and 35
LCM is 40, which is the multiple of the highest power of prime factors in the given numbers (23 x 5).
5 5 x 7 = 35 The LCM is 35.
The LCM of 18 and 20 is 180 Using factorisation method: 18 = 2 x 3² 20 = 2² x 5 lcm = 2² x 3² x 5 = 180
1, 3, 5, 15, 25, 75
lcm(4, 5, 7, 8) = 420 Using the factorisation method - multiply together the highest power of all the primes across the numbers: 4 = 2² 5 = 5 7 = 7 8 = 2³ lcm = 2³ x 5 x 7 = 280

5 x 5 = 25 5 x 7 = 35 5 x 5 x 7 = 175, the LCM
