Possible the simplest math question ever.
-420 / 3 = -140.
So the numbers you need are -139 , -140 , -141.
There are no two consecutive integers whose product is 421 - the product of 20 and 21 is 420.
There are no such integers. 20*21 = 420 is too small while 21*22 = 462 is too large.
The LCM of 20 and 21 is 420. The LCM of any pair of consecutive integers is their product.
I am not sure if any two consecutive numbers can add up to an even number.
3/7 of 420 is 180.
Simply divide 75 by 420 75/420=0.1785
The least common factor of any set of positive integers is 1.
This is easiest to solve by trial-and-error. Take two consecutive numbers and multiply them, for example, 20 x 21 = 420. Since this is too low, try higher numbers. If your answer is too high, try again with lower numbers, until you find the answer.
You can write a simple equation: x + (x+1) = 420, where x is the first number. Alternatively, you can make x the second number and write x + (x - 1) = 420. Using the first one, x + x + 1 = 420, so 2x + 1 = 420. 2x = 419 (subtract 1), so x = 209.5. You can check this answer: 209.5 + 210.5 = 420.
One yard is equal to three feet. Therefore, 420 yards is equal to 420 x 3 = 1260 feet.
