LCD of 15, 19, 68 Calculator

Arrange the Inputs 15,19,68 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 19380

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(15, 19) = 1

LCD(15, 19) = ( 15 x 19 ) / 1

LCD(15, 19) = 285 / 1

LCD(15, 19) = 285

Step2:

Here we consider the LCD from the above i.e. 285 as first number and the next as 68

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

GCF(285, 68) = 1

LCD(285, 68) = ( 285 x 68 ) / 1

LCD(285, 68) = 19380 / 1

LCD(285, 68) = 19380

LCD of 15,19,68 is 19380
