LCD of 639, 172, 211 Calculator

Arrange the Inputs 639,172,211 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 23190588

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(639, 172) = 1

LCD(639, 172) = ( 639 x 172 ) / 1

LCD(639, 172) = 109908 / 1

LCD(639, 172) = 109908

Step2:

Here we consider the LCD from the above i.e. 109908 as first number and the next as 211

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

GCF(109908, 211) = 1

LCD(109908, 211) = ( 109908 x 211 ) / 1

LCD(109908, 211) = 23190588 / 1

LCD(109908, 211) = 23190588

LCD of 639,172,211 is 23190588
