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
5 2 x 2 x 3 = 12 2 x 2 x 3 x 5 = 60, the LCM
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
45
5 x 5 = 25 5 x 7 = 35 5 x 5 x 7 = 175, the LCM
