Make use of LCD Calculator to determine the Least Common Denominator of 638, 515, 328 i.e. 53885480 smallest integer divisible by all numbers.
LCD of 638, 515, 328 is 53885480
LCD(638, 515, 328) = 53885480
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
LCD of numbers 638, 515, 328 is 53885480
LCD(638, 515, 328) = 53885480
Arrange the Inputs 638,515,328 in a horizontal line separated by commas and divide them with a prime number. Note the quotients in the next row and divide with quotients with prime numbers again. Continue the process until you have all co primes in the last.
2 | 638, 515, 328 |
319, 515, 164 |
As all the numbers left in the last row are co primes you need not do the common division process further.
To obtain the Least Common Denominator, multiply the prime numbers with which you have divided the given numbers and the co primes in the last row i.e. 2 x 319 x 515 x 164 = 53885480
Therefore, LCD of 638,515,328 is 53885480
Step1:
Let's calculate the LCD of first two numbers
The formula of LCD is LCD(a,b) = ( a x b) / GCF(a,b)
GCF(638, 515) = 1
LCD(638, 515) = ( 638 x 515 ) / 1
LCD(638, 515) = 328570 / 1
LCD(638, 515) = 328570
Step2:
Here we consider the LCD from the above i.e. 328570 as first number and the next as 328
The formula of LCD is LCD(a,b) = ( a x b) / GCF(a,b)
GCF(328570, 328) = 2
LCD(328570, 328) = ( 328570 x 328 ) / 2
LCD(328570, 328) = 107770960 / 2
LCD(328570, 328) = 53885480
LCD of 638,515,328 is 53885480
