LCD of 432, 675, 840 Calculator

Arrange the Inputs 432,675,840 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.

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 2 x 2 x 3 x 3 x 3 x 5 x 2 x 5 x 7 = 75600

Therefore, LCD of 432,675,840 is 75600

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(432, 675) = 27

LCD(432, 675) = ( 432 x 675 ) / 27

LCD(432, 675) = 291600 / 27

LCD(432, 675) = 10800

Step2:

Here we consider the LCD from the above i.e. 10800 as first number and the next as 840

The formula of LCD is LCD(a,b) = ( a x b) / GCF(a,b)

GCF(10800, 840) = 120

LCD(10800, 840) = ( 10800 x 840 ) / 120

LCD(10800, 840) = 9072000 / 120

LCD(10800, 840) = 75600

LCD of 432,675,840 is 75600
