20.
9 and 15
Any multiple of 45 greater than 180, starting with 225.
Which number is a factor of 10 , but not a multiple of 5
multiple
15 is a factor of 150, 150 is a multiple of 15.
510. To be divisible by 3, it must be a multiple of 3. Thus the required number is a multiple of both 3 and 5, which will be a multiple of their lcm: lcm(3, 5) = 15. → 495 ÷ 15 = 33 → first multiple of 15 greater than 495 is 15 x 34 = 510 → 525 ÷ 15 = 35 → last multiple of 5 less than 525 is 15 x 34 x 510 → number required is 510.
