Nov 30, 2016. LCM (10;4;18) = 180. Explanation: Factorize the three numbers: 10 = 2 ⋅ 5. 4 = 22. 18 = 2 ⋅ 32. The least common multiple is the product of all prime factors present in at least one number, taken once with the highest exponent: LCM = 22 ⋅ 32 ⋅ 5 = 4 ⋅ 9 ⋅ 5 = 180.

2 × 15 = 30. 3 × 10 = 30. So the LCM is 30. Answer link. 30 Observe that 10 is less than 15 so the multiple has to be bigger than 10. Any whole number multiple of 10 will have 0 as its last digit. 2 will be a factor of the LCM so it can not be an odd number. The multiple of 15 can only have 5 or 0 as its last digit.

18 is the LCM Since the question is asking for the least common multiple, you factor out the 6 in 18 and 6. This gives you 631 as the LCM because you have factored out 6 and this is the GCF because there are no more common factors between 3 and 1. Since 631 equals 18, 18 is the LCM.

Explanation: Multiply 10 by any whole number and the last digit will be 0. So we need the first multiple of 4 that will give a 0 as the last digit. This is 4 × 5 = 20. So the LCM = 20. LCM=20 multiples of 10: {10,color (red) (20),30,40,50,...} multiples 4: {4,8,12,16,color (red) (20),24,28,32,36,40,...} common multiples {20,40,....} The first ...

The general rule is to decompose the numbers into prime factors and then the lcm in the product of all factors raised to the highest power found in those numbers. #8=2^3# #10=2xx5# #12=2^2xx3# #lcm(8,10,12)= 2^3xx3xx5=120#

40 One way is to list the multiples of each number, then choose the common multiples, then the least one. multiples of""8:{8,16,24,32,color(blue)(40),48,56,64,72 ...

The method with prime factors is to use the maximum count of factors for any one the numbers given and multiply them all together. So we have: So we have: (2 ×2 ×2) ×(3) × (5) = 120. The least common multiple of 10, 12, and 8 is 120. You know that twelve and ten have a common multiple every sixty.

LCM(2,8)=8 the simplest way is to write down the multiples of each number and pick out the common ones multiples 2:{2,4,6,color(red)(8),10,12,14,color(red)(16),18 ...

See explanation... Alright, first we need to look at the what an LCM is. A least common multiple (LCM) is the lowest multiple that two or more numbers share. For example, the numbers 2 and 8, the LCM would be 8 based on the following set of multiples: Multiples of 2: 2, 4, 6, 8, 10, 12, 14,... Multiples of 8: 8, 16, 24, 32, 40, 48, 56,... So lets look at the LCM of 8 and 14 now. How I like to ...

The LCM is 120. Explanation: LCM means least common multiple. We can use prime factorization of each given number to determine the LCM. 6: 2 ×3. 8: 2 ×2 × 2. 5: 5. Multiply each factor the maximum times it occurs in the three numbers. LCM = 3 ×2 ×2 ×2 ×5 = 120.
