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
Well, isn't that a happy little question! To find the Least Common Multiple (LCM) of 5, 6, and 11, we can start by listing the multiples of each number and then find the smallest number that is a multiple of all three. The LCM of 5, 6, and 11 is 330. Just like painting a beautiful landscape, finding the LCM is all about patience and taking it one step at a time.
2 x 2 x 5 = 20 The LCM is 20wy.
Two or more numbers are normally needed to find 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
To find the greatest common factor (GCF) of 15 and 20 using the listing method, we first list the factors of each number. The factors of 15 are 1, 3, 5, and 15. The factors of 20 are 1, 2, 4, 5, 10, and 20. The common factor between both numbers is 5, so the GCF of 15 and 20 is 5.
45
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
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.
