Remarks on the behaviour of flow of a three-dimensional perfect fluid in the presence of a small perturbation of the initial velocity field Euler equations of the three-dimensional motion of a perfect incompressible fluid, linearized for a nearly stationary flow are considered and the class of sta...
Is the greatest common factor an odd number and even number is always even? No. Odd numbers only have odd factors. They could not have an even factor in common. How do you find highest odd factor of a number? If the number is odd, that's the answer. If the number is even, write...

We are looking for the probability that a randomly chosen factor of 21! will be odd numbers that do not contain multiples of 2 as factors. From our earlier observation, the only factors of 21! that are even are ones with at least one multiplier of 2, so our probability of finding an ...
