Make use of LCD Calculator to determine the Least Common Denominator of 505, 327, 640 i.e. 21137280 smallest integer divisible by all numbers.
LCD of 505, 327, 640 is 21137280
LCD(505, 327, 640) = 21137280
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
LCD of numbers 505, 327, 640 is 21137280
LCD(505, 327, 640) = 21137280
Arrange the Inputs 505,327,640 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 | 505, 327, 640 |
101, 327, 128 |
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 101 x 327 x 128 = 21137280
Therefore, LCD of 505,327,640 is 21137280
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(505, 327) = 1
LCD(505, 327) = ( 505 x 327 ) / 1
LCD(505, 327) = 165135 / 1
LCD(505, 327) = 165135
Step2:
Here we consider the LCD from the above i.e. 165135 as first number and the next as 640
The formula of LCD is LCD(a,b) = ( a x b) / GCF(a,b)
GCF(165135, 640) = 5
LCD(165135, 640) = ( 165135 x 640 ) / 5
LCD(165135, 640) = 105686400 / 5
LCD(165135, 640) = 21137280
LCD of 505,327,640 is 21137280
