For example, 10 is a multiple of 5 because 5 × 2 = 10, so 10 is divisible by 5 and 2. Because 10 is the smallest positive integer that is divisible by both 5 and 2, it is the least common multiple of 5 and 2. By the same principle, 10 is the least common multiple of −5 and −2 as well.
One method of producing a longer period is to sum the outputs of several LCGs of different periods having a large least common multiple; the Wichmann–Hill generator is an example of this form. (We would prefer them to be completely coprime , but a prime modulus implies an even period, so there must be a common factor of 2, at least.)

[14] and whose period is the least common multiple of the component periods. Although the periods will share a common divisor of 2, the moduli can be chosen so that is the only common divisor and the resultant period is (m 1 − 1)(m 2 − 1)···(m k − 1)/2 k−1. [2]: 744 One example of this is the Wichmann–Hill generator.
In computer science, Tarjan's off-line lowest common ancestors algorithm is an algorithm for computing lowest common ancestors for pairs of nodes in a tree, based on the union-find data structure.
Many shortcuts (such as Ctrl+Z, Alt+E, etc.) are just common conventions and are not handled by the operating system. Whether such commands are implemented (or not) depends on how an actual application program (such as an editor) is written and the frameworks used.
The following is an example algorithm designed for use in 32-bit computers: [2] = LCGs are used with the following properties: = = = = = = The CLCG algorithm is set up as follows: The seed for the first LCG, Y 0 , 1 {\displaystyle Y_{0,1}} , should be selected in the range of [1, 2147483562].
Long division is the standard algorithm used for pen-and-paper division of multi-digit numbers expressed in decimal notation. It shifts gradually from the left to the right end of the dividend, subtracting the largest possible multiple of the divisor (at the digit level) at each stage; the multiples then become the digits of the quotient, and the final difference is then the remainder.
