LCD of 489,285,978 is 92910

Arrange the Inputs 489,285,978 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.

3 489, 285, 978
163 163, 95, 326
1, 95, 2

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 163 x 1 x 95 x 2 = 92910

Therefore, LCD of 489,285,978 is 92910

Finding LCD of 489,285,978 using GCF Formula

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(489, 285) = 3

LCD(489, 285) = ( 489 x 285 ) / 3

LCD(489, 285) = 139365 / 3

LCD(489, 285) = 46455


Step2:

Here we consider the LCD from the above i.e. 46455 as first number and the next as 978

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

GCF(46455, 978) = 489

LCD(46455, 978) = ( 46455 x 978 ) / 489

LCD(46455, 978) = 45432990 / 489

LCD(46455, 978) = 92910

LCD of 489,285,978 is 92910
