(Seventy-eight)
Finding LCM for 26 and 39 using GCF's of these numbers
The first method to find LCM for numbers 26 and 39 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 26 and 39 is 13, so
LCM = (26 × 39) ÷ 13
LCM = 1014 ÷ 13
LCM = 78
