LCD of 83, 689, 138 Calculator

Arrange the Inputs 83,689,138 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 7891806

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(83, 689) = 1

LCD(83, 689) = ( 83 x 689 ) / 1

LCD(83, 689) = 57187 / 1

LCD(83, 689) = 57187

Step2:

Here we consider the LCD from the above i.e. 57187 as first number and the next as 138

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

GCF(57187, 138) = 1

LCD(57187, 138) = ( 57187 x 138 ) / 1

LCD(57187, 138) = 7891806 / 1

LCD(57187, 138) = 7891806

LCD of 83,689,138 is 7891806
