ufunc Finding LCM

This lesson is part of NumPy · All levels

Summary

Calculates the smallest common multiple (LCD) of two integers, both scalar and array. This function is element-wise so you can count multiple pairs at once. The concept of LCM often arises in the problems of periodicity, scheduling, and fractional simplification.

Key points

Np.lcm(a, b) returns the KPI of two integers.
Work with the elements-wise on the pair of array elements.
Np.lcm.reduce counts the KPK of the entire array element.
The negative input will be normalized to its absolute value.
