Answer 1

heya...!!!!

the least no. divisible by all the no. from 1 to 10
will be the lcm of those no.

1 = 1
2= 2 × 1
3= 3 × 1
4= 2 × 2
5= 5 × 1
6= 3 × 2
7= 7 × 1
8= 4 × 2
9= 3 × 3
10= 5 × 2

l.c.m of those no. = 1 × 2 × 2 × 2 × 3 × 3 × 5 × 7

=> 2520

hence least no. divisible by all the no. from 1 to 10 is 2520
