LCD of 638, 445, 645 Calculator

Arrange the Inputs 638,445,645 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. 5 x 638 x 89 x 129 = 36624390

Therefore, LCD of 638,445,645 is 36624390

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(638, 445) = 1

LCD(638, 445) = ( 638 x 445 ) / 1

LCD(638, 445) = 283910 / 1

LCD(638, 445) = 283910

Step2:

Here we consider the LCD from the above i.e. 283910 as first number and the next as 645

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

GCF(283910, 645) = 5

LCD(283910, 645) = ( 283910 x 645 ) / 5

LCD(283910, 645) = 183121950 / 5

LCD(283910, 645) = 36624390

LCD of 638,445,645 is 36624390
