LCM for 648 and 1,029

The first method to find LCM for numbers 648 and 1,029 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 648 and 1,029 is 3, so

LCM = (648 × 1,029) ÷ 3

LCM = 666,792 ÷ 3

LCM = 222,264

The second method to find LCM for numbers 648 and 1,029 is to list out the common multiples for both numbers and pick the first one that matches:
