LCD of 641, 121, 405 Calculator

Arrange the Inputs 641,121,405 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 31412205

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(641, 121) = 1

LCD(641, 121) = ( 641 x 121 ) / 1

LCD(641, 121) = 77561 / 1

LCD(641, 121) = 77561

Step2:

Here we consider the LCD from the above i.e. 77561 as first number and the next as 405

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

GCF(77561, 405) = 1

LCD(77561, 405) = ( 77561 x 405 ) / 1

LCD(77561, 405) = 31412205 / 1

LCD(77561, 405) = 31412205

LCD of 641,121,405 is 31412205
