User question:
user: I need to calculate the least common multiples for a set of number pairs for a small programming project I'm working on. Could you determine the LCMs for the pairs 35 and 45, 72 and 108, 120 and 180, and 200 and 300? These calculations will help me optimize a part of my code related to scheduling tasks.

Available functions:
name: math_lcm
description: Calculates the least common multiple of two numbers.
parameters: type: dict
properties: a: type: integer
description: The first number. This should be the larger number.
b: type: integer
description: The second number.
required: a
b

Ground-truth function call(s):
math_lcm(a=45, b=35)
math_lcm(a=72, b=108)
math_lcm(a=120, b=180)
math_lcm(a=200, b=300)
