First, get the prime factorization of 18 and 32:
18= 2x3x3 or 2x32
32= 2x2x2x2x2 or 25
GCF: Get the common factors of 18 and 32
18=...2 ............3..3
32=...2 2 2 2 2
------------------------------------------
GCF= 2
LCM:
18=...2.....................3..3
32=...2...2...2...2...2
------------------------------------------
LCM=2 x2 x2 x 2 x 2x3x3
=288
Therefore, the GCF=2 and the LCM=288.
The least common multiple of 9 and 18 is 18. Because 18 is a multiple of 9, it is automatically the LCM. You can also find the LCM of a pair of numbers by dividing their product by their GCF. The product of 9 and 18 is 162. The GCF of 9 and 18 is 9. (Because 9 is a factor of 18, it is automatically the greatest common factor of the pair.) So the least common multiple of 9 and 18 is 162/9 = 18. Another strategy for finding the LCM is listing the multiples of each number, then finding the lowest multiple that is in both lists. The multiples of 9 are 9, 18, 27, and so on. The multiples of 18 are 18, 36, 54, and so on. So the LCM of 9 and 18 is 18.
The LCM is 18.
The LCM is: 18
LCM of 2 6 and 18 is 18.
The LCM of 18 and 6 is 18. The LCM of 18 and 6v is 18v.
LCM of 18 and 84 is 252.
The LCM of 16 and 18 is 144.
lcm(70, 18) = 630. Write 70 and 18 in their prime factorisation in power format. The LCM is the product of the primes to their highest power: 70 = 2 x 5 x 7 18 = 2 x 32 lcm = 2 x 32 x 5 x 7 = 630
The LCM of 1015 and 18 is 18270. The LCM of 10, 15 and 18 is 90.
The LCM is 18
The LCM is: 18
The least common multiple (LCM) of 18 and 58 is 232.
