(Three hundred sixty-four)
Finding LCM for 28 and 52 using GCF's of these numbers
The first method to find LCM for numbers 28 and 52 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 28 and 52 is 4, so
LCM = (28 × 52) ÷ 4
LCM = 1456 ÷ 4
LCM = 364
