The least number that is divisible by all the number from 1 to 10 (both inclusive)
A. 10

B. 100

C. 504

D. 2520

Answer :

Factors of 1 to 10 numbers


1 = 1


2 = 1 × 2


3 = 1 × 3


4 = 1 × 2 × 2


5 = 1 × 5


6 = 1 × 2 × 3


7 = 1 × 7


8 = 2 × 2 × 2


9 = 1 × 3 × 3


LCM of number 1 to 10 = LCM (1, 2, 3, 4, 5, 6, 7, 8, 9, 10)


= 1 × 2 × 2 × 2 × 3 × 3 × 5 × 7 = 2520
