11. Find the least number which is exactly divided by 28,36,45 when we add 19 to it
`"Required number" = ( "LCM of " 28,36,45 ) - 19 = 1260 - 19 = 1241`.
| 2 | 28 | | 36 | | 45 | | 2 | 14 | | 18 | | 45 | | 3 | 7 | | 9 | | 45 | | 3 | 7 | | 3 | | 15 | | 5 | 7 | | 1 | | 5 | | 7 | 7 | | 1 | | 1 | | | 1 | | 1 | | 1 |
LCM of 28,36,45 = 2 × 2 × 3 × 3 × 5 × 7 = 1260
