Question

find the smallest no of six digit 18,24,30​

Answer 1

LCM of 18,24,30 is 360 by prime factorization

Let the smallest six digit number be 100000

∵100000÷360=277.78

which implies that the six digit number divisible by 18,24,30 can be given as

278×360=100080

Answer 2

Answer:100296

Step-by-step explanation:The LCM of 18, 24 and 42 is 504, the lowest number which is divisible by 18, 24 and 42. The next number will be next multiple of 504 and so on and so forth.

Now, come to your point: the smallest number of 6 digits is 100000 when divided by 504 gives an answer of 198.41 that means a multiple of 504 near 100000 is

504 X 198 which is 99792 but it is a 5-digit number hence the next multiple of 504 which satisfies your query is 99792 + 504 =100296 which is the smallest 6-digit number that is divisible by 18, 24 and 42.
