Question

The product of four consecutive positive integers is $840$, then the numbers are $4,5,6,7$.

State true or false.

• A. True
• B. False

Answer 1

The correct option is A True

Let the four consecutive integers be, $n,n+1,n+2,n+3$
then, $n(n+1)(n+2)(n+3)=840$
$n(n+1)(n+2)(n+3)=4\times 5\times 6\times 7$
Comparing, we get $n=4$
Thus, the numbers are $4,5,6,7$
