#### What is LCM?

In mathematics, least common multiple, which is ordinarily reffered to as LCM is characterized as the smallest non-zero number which is divisible by both given numbers 54 and 60.

#### Properties of LCM

• LCM follows associative property, that means LCM(54, 60) = LCM(60, 54).
• LCM follows commutative property, which means LCM(a, b, c) = LCM(LCM(a, b), c) = LCM(a, LCM(b, c)).
• LCM follows distributive property, which means LCM(ab, bc, ad) = d * LCM(x, y, z).
• The LCM of two given numbers is never less than any of those numbers. Eg- LCM of 54 and 60 is 540, where 54 and 60 are less than 540.
• The LCM of two or more prime numbers is their product.

### Example: Find lcm of 54 and 60 by Listing Method

• Multiples of 54: 54, 108, 162, 216, 270, 324, 378, 432, 486, 540, 594, 648, 702, 756, 810, 864, 918, 972, 1026, 1080, 1134, 1188, 1242, 1296, 1350, 1404, 1458, 1512, 1566, 1620, 1674, 1728, 1782, 1836, 1890, 1944, 1998, 2052, 2106, 2160, 2214, 2268, 2322, 2376, 2430, 2484, 2538, 2592, 2646, 2700, 2754, 2808, 2862, 2916, 2970, 3024, 3078, 3132, 3186, 3240
• Multiples of 60: 60, 120, 180, 240, 300, 360, 420, 480, 540, 600, 660, 720, 780, 840, 900, 960, 1020, 1080, 1140, 1200, 1260, 1320, 1380, 1440, 1500, 1560, 1620, 1680, 1740, 1800, 1860, 1920, 1980, 2040, 2100, 2160, 2220, 2280, 2340, 2400, 2460, 2520, 2580, 2640, 2700, 2760, 2820, 2880, 2940, 3000, 3060, 3120, 3180, 3240

Hence, LCM of 54 and 60 is 540.

### Example: Find lcm of 54 and 60 by Common Division Method

 2 54 60 2 27 30 3 27 15 3 9 5 3 3 5 5 1 5 1 1

Hence, LCM of 54 and 60 is 2 x 2 x 3 x 3 x 3 x 5 = 540.

### Example: Find lcm of 54 and 60 by Formula

• GCF of 54 and 60 = 6
• LCM of 54 and 60 = (54 x 60) / 6
• => 3240 / 6

Hence, LCM of 54 and 60 is 540.

#### Examples
