Question

When 21 is added to a number the result is divisible by 3,8,9,12,16,18 find the least among number

Answer 1

Answer:

3,8,9,12,16, 18 take lcm of numbers

we will get 144 subtract 21 from this number

new number will be

144-21 =123

by this if we wants to find least of such number it will be unlimited or infinity number

some least of number will be given below

1)144x1=144-21=123

2) 144x2 =288 -21 =267

3)144x3 =432-21= 411

4)144x4-21 =576-21=555

5)144x5-21 =720-21=699
