Solution
The correct option is C 2520
1 = 1
2 = 1*2
3 = 1*3
4 = 1*2*2
5 = 1*5
6 = 1*2*3
7 = 1*7
8 = 1*2*2*2
9 = 1*3*3
10 = 1*2*5
LCM of number 1 to 10 = LCM(1,2,3,4,5,6,7,8,9,10)
LCM of number 1 to 10= 1*2*2*2*3*3*5*7 = 2520
1 = 1
2 = 1*2
3 = 1*3
4 = 1*2*2
5 = 1*5
6 = 1*2*3
7 = 1*7
8 = 1*2*2*2
9 = 1*3*3
10 = 1*2*5
LCM of number 1 to 10 = LCM(1,2,3,4,5,6,7,8,9,10)
LCM of number 1 to 10= 1*2*2*2*3*3*5*7 = 2520
