Any multiple of 300 will also be a multiple of 12 and 50. The prime factors of 12 are 2, 2, 3 The prime factors of 50 are 2, 5, 5 So the Least Common Multiple of 12 and 50 is 2x2x3x5x5 = 300
30
30 or 40
As factors, 1 and 5. As multiples, any multiple of 50
It is 30.
LCM of (a) and (b) is given as (ab)/(GCF(a,b)) To find the GCF, factor and find common factors. 50 factors to [2 5 5] 80 factors to [2 2 2 2 5] Common factors are [2 5] = 10 50 * 80 / 10 = 400 ■
30
Factors: 1, 5, 25 Multiples: 25, 50, 75, 100 and so on.
50 is the least common multiple of 50 and 10.
It is impossible to be a factor of 1000, but not of 10000. All of the factors of 1000 are also factors of 10000.
It's a multiple of 5, a multiple of 6 (since it's between twin primes), and less than 50. The only possibility is 30. To check: The factors of 30 are 1, 2, 3, 5, 6, 10, 15, and 30
The hundredth multiple of 50 is 100 x 50 = 5000
