900
One example is 1 + 899.
With big LCM's like this, I use this method. Although not the most accurate it works: 9 x 8 x 25= 1800 this means all three numbers can go into 1800 1800/2 = 900 this is to try to find a smaller number into which all three numbers go into Now check: 900/9=100 900/8=114 900/25 = 36 now that we know 900 is divisible by all three numbers we know it is a multiple of all three
Even numbers
There are no numbers between 900 and 1,100 that are divisible by 10 but not by two.
The numbers that go into 146 is 2 and 4.
An infinite number of numbers can be divided by 450. The smallest two numbers that can be divided by 450 are 450 (450 divided by 450 equals 1) and 900 (900 divided by 450 equals 2).
