LCD of 643, 170, 151 Calculator

Arrange the Inputs 643,170,151 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 16505810

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(643, 170) = 1

LCD(643, 170) = ( 643 x 170 ) / 1

LCD(643, 170) = 109310 / 1

LCD(643, 170) = 109310

Step2:

Here we consider the LCD from the above i.e. 109310 as first number and the next as 151

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

GCF(109310, 151) = 1

LCD(109310, 151) = ( 109310 x 151 ) / 1

LCD(109310, 151) = 16505810 / 1

LCD(109310, 151) = 16505810

LCD of 643,170,151 is 16505810
