LCM for 50 and 100

The first method to find LCM for numbers 50 and 100 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 50 and 100 is 50, so

LCM = (50 × 100) ÷ 50

LCM = 5000 ÷ 50

LCM = 100

The second method to find LCM for numbers 50 and 100 is to list out the common multiples for both nubmers and pick the first which matching:

Multiples of 50: 50, 100, 150, 200

Multiples of 100: 100, 200, 300, 400, 500, 600, 700, 800, 900, 1000, 1100, 1200, 1300, 1400, 1500, 1600, 1700, 1800, 1900, 2000, 2100, 2200, 2300, 2400, 2500, 2600, 2700, 2800, 2900, 3000, 3100, 3200,
