LCD of 387, 623, 421 Calculator

Arrange the Inputs 387,623,421 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.

Given numbers has no common factors except 1. So, there LCD is their product i.e 101503521

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(387, 623) = 1

LCD(387, 623) = ( 387 x 623 ) / 1

LCD(387, 623) = 241101 / 1

LCD(387, 623) = 241101

Step2:

Here we consider the LCD from the above i.e. 241101 as first number and the next as 421

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

GCF(241101, 421) = 1

LCD(241101, 421) = ( 241101 x 421 ) / 1

LCD(241101, 421) = 101503521 / 1

LCD(241101, 421) = 101503521

LCD of 387,623,421 is 101503521
