210.
Less than.
400 is one such multiple.
Any multiple of 20 that is greater than 400. If the multiple is 400 or fewer then the length of the rectangle will be less than (or equal to) its width which contradicts the definition of the length as the longer side of a rectangle.
The least common multiple of 400 and 4,500 is 18,000.
All multiples of their lowest common multiple: lcm(3, 5, 7) = 105 → the numbers less than 400 with 3, 5, 7 as factors are: 105, 210, 315.
400 meter is less than 1 km
400
400 - 327 = 73
3020 − 400 = 2620
Less, 400 decimeters = 4000 centimeters
25% less.
It is 402.
