LCD of 47, 53, 20 Calculator

Arrange the Inputs 47,53,20 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 49820

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(47, 53) = 1

LCD(47, 53) = ( 47 x 53 ) / 1

LCD(47, 53) = 2491 / 1

LCD(47, 53) = 2491

Step2:

Here we consider the LCD from the above i.e. 2491 as first number and the next as 20

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

GCF(2491, 20) = 1

LCD(2491, 20) = ( 2491 x 20 ) / 1

LCD(2491, 20) = 49820 / 1

LCD(2491, 20) = 49820

LCD of 47,53,20 is 49820
