LCM for 55 and 61
What's the Least Common Multiple (LCM) of 55 and 61?
(Three thousand, three hundred fifty-five)
Finding LCM for 55 and 61 using GCF's of these numbers
The first method to find LCM for numbers 55 and 61 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 55 and 61 is 1, so
LCM = (55 × 61) ÷ 1
LCM = 3355 ÷ 1
LCM = 3355
