LCM for 18 and 250

The first method to find LCM for numbers 18 and 250 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 18 and 250 is 2, so

LCM = (18 × 250) ÷ 2

LCM = 4,500 ÷ 2

LCM = 2,250

The second method to find LCM for numbers 18 and 250 is to list out the common multiples for both numbers and pick the first one that matches:
