LCD of 69, 168, 630 Calculator

Arrange the Inputs 69,168,630 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 3 x 7 x 23 x 4 x 15 = 57960

Therefore, LCD of 69,168,630 is 57960

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(69, 168) = 3

LCD(69, 168) = ( 69 x 168 ) / 3

LCD(69, 168) = 11592 / 3

LCD(69, 168) = 3864

Step2:

Here we consider the LCD from the above i.e. 3864 as first number and the next as 630

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

GCF(3864, 630) = 42

LCD(3864, 630) = ( 3864 x 630 ) / 42

LCD(3864, 630) = 2434320 / 42

LCD(3864, 630) = 57960

LCD of 69,168,630 is 57960
