LCD of 139, 721, 231 Calculator

Arrange the Inputs 139,721,231 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. 7 x 139 x 103 x 33 = 3307227

Therefore, LCD of 139,721,231 is 3307227

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(139, 721) = 1

LCD(139, 721) = ( 139 x 721 ) / 1

LCD(139, 721) = 100219 / 1

LCD(139, 721) = 100219

Step2:

Here we consider the LCD from the above i.e. 100219 as first number and the next as 231

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

GCF(100219, 231) = 7

LCD(100219, 231) = ( 100219 x 231 ) / 7

LCD(100219, 231) = 23150589 / 7

LCD(100219, 231) = 3307227

LCD of 139,721,231 is 3307227
