LCM for 60 and 455

The first method to find LCM for numbers 60 and 455 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 60 and 455 is 5, so

LCM = (60 × 455) ÷ 5

LCM = 27,300 ÷ 5

LCM = 5,460

The second method to find LCM for numbers 60 and 455 is to list out the common multiples for both numbers and pick the first one that matches:
