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 359,248,570
We can find the LCD of numbers 359,248,570 by the prime factorization method or by applying the LCD formula.
The LCD of 359,248,570 is 25374120.
2 | 359, 248, 570 |
359, 124, 285 |
As you can see, now we have to multiply the prime numbers on the left side with the co-primes at the bottom.
2 x 359 x 124 x 285 = 25374120
Thus, we have determined that the LCD of 359,248,570 is 25374120
The LCD formula is LCD(a,b) = ( a x b) / GCF(a,b)
Step1:
Find the GCF of 359 and 248. To find the GCF, list down the factors of 359 and 248 and select the highest factor that appears in both lists of factors.
359 : [1, 359]
248 : [1, 2, 4, 8, 31, 62, 124, 248]
From this, we can see that the GCF of 359 and 248 is 1.
Now, put this into the LCD formula.
LCD(359, 248) = ( 359 x 248 ) / 1
LCD(359, 248) = 89032 / 1
LCD(359, 248) = 89032
Step2:
Find the GCF of 89032 and 570. To find the GCF, list down the factors of 89032 and 570 and select the highest factor that appears in both lists of factors.
89032 : [1, 2, 4, 8, 31, 62, 124, 248, 359, 718, 1436, 2872, 11129, 22258, 44516, 89032]
570 : [1, 2, 3, 5, 6, 10, 15, 19, 30, 38, 57, 95, 114, 190, 285, 570]
From this, we can see that the GCF of 89032 and 570 is 2.
Now, put this into the LCD formula.
LCD(89032, 570) = ( 89032 x 570 ) / 2
LCD(89032, 570) = 50748240 / 2
LCD(89032, 570) = 25374120
LCD of 359,248,570 is 25374120
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 .
