#### What does LCM mean in mathematics?

The least common multiple or LCM of two numbers 48 and 64 is defined as the smallest positive integer which is divisible by both of them. It is represented by LCM(48, 64).

#### Properties of LCM

• The LCM of two given numbers is never less than any of those numbers. Eg- LCM of 48 and 64 is 192, where 48 and 64 are less than 192.
• LCM is associative which means LCM(48, 64) = LCM(64, 48).
• LCM is commutative which means LCM(a, b, c) = LCM(LCM(a, b), c) = LCM(a, LCM(b, c)).
• LCM is distributive, which means LCM(ab, bc, ad) = d * LCM(x, y, z).
• The LCM of two or more prime numbers is their product.

### Example: Find lcm of 48 and 64 by Listing Method

• Multiples of 48: 48, 96, 144, 192, 240, 288, 336, 384, 432, 480, 528, 576, 624, 672, 720, 768, 816, 864, 912, 960, 1008, 1056, 1104, 1152, 1200, 1248, 1296, 1344, 1392, 1440, 1488, 1536, 1584, 1632, 1680, 1728, 1776, 1824, 1872, 1920, 1968, 2016, 2064, 2112, 2160, 2208, 2256, 2304, 2352, 2400, 2448, 2496, 2544, 2592, 2640, 2688, 2736, 2784, 2832, 2880, 2928, 2976, 3024, 3072
• Multiples of 64: 64, 128, 192, 256, 320, 384, 448, 512, 576, 640, 704, 768, 832, 896, 960, 1024, 1088, 1152, 1216, 1280, 1344, 1408, 1472, 1536, 1600, 1664, 1728, 1792, 1856, 1920, 1984, 2048, 2112, 2176, 2240, 2304, 2368, 2432, 2496, 2560, 2624, 2688, 2752, 2816, 2880, 2944, 3008, 3072

Hence, LCM of 48 and 64 is 192.

### Example: Find lcm of 48 and 64 by Common Division Method

 2 48 64 2 24 32 2 12 16 2 6 8 2 3 4 2 3 2 3 3 1 1 1

Hence, LCM of 48 and 64 is 2 x 2 x 2 x 2 x 2 x 2 x 3 = 192.

### Example: Find lcm of 48 and 64 by Formula

• GCF of 48 and 64 = 16
• LCM of 48 and 64 = (48 x 64) / 16
• => 3072 / 16

Hence, LCM of 48 and 64 is 192.

#### Examples

Franky and Joy are running on a circular track. They start at the same time. They take 48 and 64 minutes respectively to go round once. Find at what time they will run together?

Franky and Joy are running on a circular track. They take 48 and 64 minutes respectively to go round once. We need to find out at what time (minimum) they will run together again. For this we need to find the LCM of 48 and 64.
So, LCM of 48 and 64 is 192.

The least number of candies and chocolates Annie should buy so that there will be one candy for each chocolate we need to find the lcm of 48 and 64.
So, LCM of 48 and 64 is 192.

Both the cricket team and the rugby team had games, today. The cricket team plays every 48 days and the basketball team plays every 64 days. When will both teams have games on the same day again?

Given that the cricket team plays every 48 days and the basketball team plays every 64 days, so for finding the next time when both teams will play again we need to find the LCM of 48 and 64.
So, LCM of 48 and 64 is 192.

Sammy's company prints 48 textbooks at a time. Daniel's company prints textbooks in sets of 64 at a time. According to a survey done by a committee, both companies printed the same number of textbooks last year. Find the least number of books that each company would have printed.

To find the least number of textbooks that each company could have printed we need to find the LCM of 48 and 64.
So, LCM of 48 and 64 is 192.

Ariel exercises every 48 days and Rubel every 64 days. They both excercised today. How many days will it be until they excercise together again?
