LCD of 129,142,978 is 2985834

Arrange the Inputs 129,142,978 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.

2 129, 142, 978
3 129, 71, 489
43, 71, 163

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 43 x 71 x 163 = 2985834

Therefore, LCD of 129,142,978 is 2985834

Finding LCD of 129,142,978 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(129, 142) = 1

LCD(129, 142) = ( 129 x 142 ) / 1

LCD(129, 142) = 18318 / 1

LCD(129, 142) = 18318


Step2:

Here we consider the LCD from the above i.e. 18318 as first number and the next as 978

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

GCF(18318, 978) = 6

LCD(18318, 978) = ( 18318 x 978 ) / 6

LCD(18318, 978) = 17915004 / 6

LCD(18318, 978) = 2985834

LCD of 129,142,978 is 2985834
