LCM for 25 and 50

The first method to find LCM for numbers 25 and 50 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 25 and 50 is 25, so

LCM = (25 × 50) ÷ 25

LCM = 1250 ÷ 25

LCM = 50

The second method to find LCM for numbers 25 and 50 is to list out the common multiples for both nubmers and pick the first which matching:

Multiples of 25: 25, 50, 75, 100

Multiples of 50: 50, 100, 150, 200, 250, 300, 350, 400, 450, 500, 550, 600, 650, 700, 750, 800, 850, 900, 950, 1000, 1050, 1100, 1150, 1200, 1250, 1300, 1350, 1400, 1450, 1500, 1550, 1600, 1650, 1700,
