LCD of 28, 31, 13 Calculator

Arrange the Inputs 28,31,13 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 11284

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(28, 31) = 1

LCD(28, 31) = ( 28 x 31 ) / 1

LCD(28, 31) = 868 / 1

LCD(28, 31) = 868

Step2:

Here we consider the LCD from the above i.e. 868 as first number and the next as 13

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

GCF(868, 13) = 1

LCD(868, 13) = ( 868 x 13 ) / 1

LCD(868, 13) = 11284 / 1

LCD(868, 13) = 11284

LCD of 28,31,13 is 11284
