LCD of 243, 445, 689 Calculator

Arrange the Inputs 243,445,689 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 74505015

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(243, 445) = 1

LCD(243, 445) = ( 243 x 445 ) / 1

LCD(243, 445) = 108135 / 1

LCD(243, 445) = 108135

Step2:

Here we consider the LCD from the above i.e. 108135 as first number and the next as 689

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

GCF(108135, 689) = 1

LCD(108135, 689) = ( 108135 x 689 ) / 1

LCD(108135, 689) = 74505015 / 1

LCD(108135, 689) = 74505015

LCD of 243,445,689 is 74505015
