If the product of three continuous natural numbers is 336, what is the sum of them,
6 + 7 + 8 = 21, because 6 * 7 * 8 = 336
The product of three continuous natural numbers is 336. The three natural numbers are______ ．
336 = 2 × 2 × 2 × 3 × 7 = 8 × 6 × 7, so the three natural numbers are 6, 7 and 8 respectively
The product of three continuous natural numbers is 336. The three natural numbers are______ ．
336 = 2 × 2 × 2 × 3 × 7 = 8 × 6 × 7, so the three natural numbers are 6, 7 and 8 respectively
If the product of three continuous natural numbers is 336, then their sum is?
If you're in high school
The way to do it is
(X-1)(X+1)*X=336
X^3-X-336=0
If you're in primary school
The way to do it is
7 * 7 * 7 = 343
Closest to 336
So find the middle number
And then check it out
So the answer is 7 * 3 = 21 (6 + 7 + 8 = 21 is OK)
