LCD of 21, 674, 391 Calculator

Arrange the Inputs 21,674,391 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 5534214

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(21, 674) = 1

LCD(21, 674) = ( 21 x 674 ) / 1

LCD(21, 674) = 14154 / 1

LCD(21, 674) = 14154

Step2:

Here we consider the LCD from the above i.e. 14154 as first number and the next as 391

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

GCF(14154, 391) = 1

LCD(14154, 391) = ( 14154 x 391 ) / 1

LCD(14154, 391) = 5534214 / 1

LCD(14154, 391) = 5534214

LCD of 21,674,391 is 5534214
