LCD of 129, 643, 940 Calculator

Arrange the Inputs 129,643,940 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 77970180

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(129, 643) = 1

LCD(129, 643) = ( 129 x 643 ) / 1

LCD(129, 643) = 82947 / 1

LCD(129, 643) = 82947

Step2:

Here we consider the LCD from the above i.e. 82947 as first number and the next as 940

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

GCF(82947, 940) = 1

LCD(82947, 940) = ( 82947 x 940 ) / 1

LCD(82947, 940) = 77970180 / 1

LCD(82947, 940) = 77970180

LCD of 129,643,940 is 77970180
