Make use of LCD Calculator to determine the Least Common Denominator of 20, 723, 615 i.e. 592860 smallest integer divisible by all numbers.
LCD of 20, 723, 615 is 592860
LCD(20, 723, 615) = 592860
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
LCD of numbers 20, 723, 615 is 592860
LCD(20, 723, 615) = 592860
Arrange the Inputs 20,723,615 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.
3 | 20, 723, 615 |
5 | 20, 241, 205 |
4, 241, 41 |
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. 3 x 5 x 4 x 241 x 41 = 592860
Therefore, LCD of 20,723,615 is 592860
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(20, 723) = 1
LCD(20, 723) = ( 20 x 723 ) / 1
LCD(20, 723) = 14460 / 1
LCD(20, 723) = 14460
Step2:
Here we consider the LCD from the above i.e. 14460 as first number and the next as 615
The formula of LCD is LCD(a,b) = ( a x b) / GCF(a,b)
GCF(14460, 615) = 15
LCD(14460, 615) = ( 14460 x 615 ) / 15
LCD(14460, 615) = 8892900 / 15
LCD(14460, 615) = 592860
LCD of 20,723,615 is 592860
