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 713,586,489
We can find the LCD of numbers 713,586,489 by the prime factorization method or by applying the LCD formula.
The LCD of 713,586,489 is 204313002.
Given numbers has no common factors except 1. So, there LCD is their product i.e 204313002
The LCD formula is LCD(a,b) = ( a x b) / GCF(a,b)
Step1:
Find the GCF of 713 and 586. To find the GCF, list down the factors of 713 and 586 and select the highest factor that appears in both lists of factors.
713 : [1, 23, 31, 713]
586 : [1, 2, 293, 586]
From this, we can see that the GCF of 713 and 586 is 1.
Now, put this into the LCD formula.
LCD(713, 586) = ( 713 x 586 ) / 1
LCD(713, 586) = 417818 / 1
LCD(713, 586) = 417818
Step2:
Find the GCF of 417818 and 489. To find the GCF, list down the factors of 417818 and 489 and select the highest factor that appears in both lists of factors.
417818 : [1, 2, 23, 31, 46, 62, 293, 586, 713, 1426, 6739, 9083, 13478, 18166, 208909, 417818]
489 : [1, 3, 163, 489]
From this, we can see that the GCF of 417818 and 489 is 1.
Now, put this into the LCD formula.
LCD(417818, 489) = ( 417818 x 489 ) / 1
LCD(417818, 489) = 204313002 / 1
LCD(417818, 489) = 204313002
LCD of 713,586,489 is 204313002
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 .
