LCD of 645, 617, 869 Calculator

Arrange the Inputs 645,617,869 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 345831585

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(645, 617) = 1

LCD(645, 617) = ( 645 x 617 ) / 1

LCD(645, 617) = 397965 / 1

LCD(645, 617) = 397965

Step2:

Here we consider the LCD from the above i.e. 397965 as first number and the next as 869

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

GCF(397965, 869) = 1

LCD(397965, 869) = ( 397965 x 869 ) / 1

LCD(397965, 869) = 345831585 / 1

LCD(397965, 869) = 345831585

LCD of 645,617,869 is 345831585
