Read this article to figure out how to calculate the lowest common denominator of . Learn the two different methods that you can use to find the LCD: the prime factorization method and the LCD formula method. We will explain both these methods in detail so stick around until the very end to understand. Utilise our free LCD Calculator to avail the LCD of numbers easily.
Given numbers are 819,368,101
We can find the LCD of numbers 819,368,101 by the prime factorization method or by applying the LCD formula.
The LCD of 819,368,101 is 30440592.
Given numbers has no common factors except 1. So, there LCD is their product i.e 30440592
The LCD formula is LCD(a,b) = ( a x b) / GCF(a,b)
Step1:
Find the GCF of 819 and 368. To find the GCF, list down the factors of 819 and 368 and select the highest factor that appears in both lists of factors.
819 : [1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819]
368 : [1, 2, 4, 8, 16, 23, 46, 92, 184, 368]
From this, we can see that the GCF of 819 and 368 is 1.
Now, put this into the LCD formula.
LCD(819, 368) = ( 819 x 368 ) / 1
LCD(819, 368) = 301392 / 1
LCD(819, 368) = 301392
Step2:
Find the GCF of 301392 and 101. To find the GCF, list down the factors of 301392 and 101 and select the highest factor that appears in both lists of factors.
301392 : [1, 2, 3, 4, 6, 7, 8, 9, 12, 13, 14, 16, 18, 21, 23, 24, 26, 28, 36, 39, 42, 46, 48, 52, 56, 63, 69, 72, 78, 84, 91, 92, 104, 112, 117, 126, 138, 144, 156, 161, 168, 182, 184, 207, 208, 234, 252, 273, 276, 299, 312, 322, 336, 364, 368, 414, 468, 483, 504, 546, 552, 598, 624, 644, 728, 819, 828, 897, 936, 966, 1008, 1092, 1104, 1196, 1288, 1449, 1456, 1638, 1656, 1794, 1872, 1932, 2093, 2184, 2392, 2576, 2691, 2898, 3276, 3312, 3588, 3864, 4186, 4368, 4784, 5382, 5796, 6279, 6552, 7176, 7728, 8372, 10764, 11592, 12558, 13104, 14352, 16744, 18837, 21528, 23184, 25116, 33488, 37674, 43056, 50232, 75348, 100464, 150696, 301392]
101 : [1, 101]
From this, we can see that the GCF of 301392 and 101 is 1.
Now, put this into the LCD formula.
LCD(301392, 101) = ( 301392 x 101 ) / 1
LCD(301392, 101) = 30440592 / 1
LCD(301392, 101) = 30440592
LCD of 819,368,101 is 30440592
Here are some samples of LCD of Numbers calculations.
1. What is the LCD of ?
Answer: LCD of is .
2. How to find LCD of using prime factorization ?
Answer: Just keep dividing by prime numbers until only co-primes are left over. At that point, simply multiply the co-primes with the prime numbers on the left. The answer will be , the LCD.
3. How to Find the LCD of using LCD formula ?
Answer: The LCD formula is LCD(a,b) = ( a x b) / GCF(a,b).
You must first calculate the LCD OF and . Then, find the LCD of that answer and and so on. The answer will be , which is the LCD of .
