LCD of 81, 268, 689 Calculator

Arrange the Inputs 81,268,689 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 14956812

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(81, 268) = 1

LCD(81, 268) = ( 81 x 268 ) / 1

LCD(81, 268) = 21708 / 1

LCD(81, 268) = 21708

Step2:

Here we consider the LCD from the above i.e. 21708 as first number and the next as 689

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

GCF(21708, 689) = 1

LCD(21708, 689) = ( 21708 x 689 ) / 1

LCD(21708, 689) = 14956812 / 1

LCD(21708, 689) = 14956812

LCD of 81,268,689 is 14956812
