LCM for 77 and 308
What's the Least Common Multiple (LCM) of 77 and 308?
Answer
(Three hundred eight)
Finding LCM for 77 and 308 using GCF of these numbers
The first method to find LCM for numbers 77 and 308 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 77 and 308 is 77, so
LCM = (77 × 308) ÷ 77
LCM = 23716 ÷ 77
LCM = 308
