Make use of LCD Calculator to determine the Least Common Denominator of 285, 247, 905 i.e. 670605 smallest integer divisible by all numbers.
LCD of 285, 247, 905 is 670605
LCD(285, 247, 905) = 670605
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
LCD of numbers 285, 247, 905 is 670605
LCD(285, 247, 905) = 670605
Arrange the Inputs 285,247,905 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.
5 | 285, 247, 905 |
19 | 57, 247, 181 |
3, 13, 181 |
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. 5 x 19 x 3 x 13 x 181 = 670605
Therefore, LCD of 285,247,905 is 670605
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(285, 247) = 19
LCD(285, 247) = ( 285 x 247 ) / 19
LCD(285, 247) = 70395 / 19
LCD(285, 247) = 3705
Step2:
Here we consider the LCD from the above i.e. 3705 as first number and the next as 905
The formula of LCD is LCD(a,b) = ( a x b) / GCF(a,b)
GCF(3705, 905) = 5
LCD(3705, 905) = ( 3705 x 905 ) / 5
LCD(3705, 905) = 3353025 / 5
LCD(3705, 905) = 670605
LCD of 285,247,905 is 670605
