ufunc Finding LCM

The Least Common Multiple (LCM) is the smallest multiple common to two or more integers. NumPy provides the lcm ufunc to compute the LCM of array elements efficiently.

Key Topics

Computing LCM

The lcm function computes the LCM of two or more integers, applied element-wise when used with arrays.

Example

# Finding LCM
import numpy as np

arr1 = np.array([12, 18, 24])
arr2 = np.array([15, 30, 36])

lcm = np.lcm(arr1, arr2)

print("LCM of arrays:", lcm)

Output

LCM of arrays: [60 90 72]

Explanation: The lcm ufunc computes the LCM for each pair of corresponding elements in the arrays.

Key Takeaways

  • Element-Wise LCM: Use lcm to compute the least common multiple for arrays.
  • Applications: Solve problems in number theory, scheduling, or data alignment.
  • Efficiency: Handles array computations element by element for optimal performance.
