LCD of 61, 22, 20 Calculator

Arrange the Inputs 61,22,20 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.

As all the numbers left in the last row are co primes you need not do the common division process further.

To obtain the Least Common Denominator, multiply the prime numbers with which you have divided the given numbers and the co primes in the last row i.e. 2 x 61 x 11 x 10 = 13420

Therefore, LCD of 61,22,20 is 13420

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(61, 22) = 1

LCD(61, 22) = ( 61 x 22 ) / 1

LCD(61, 22) = 1342 / 1

LCD(61, 22) = 1342

Step2:

Here we consider the LCD from the above i.e. 1342 as first number and the next as 20

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

GCF(1342, 20) = 2

LCD(1342, 20) = ( 1342 x 20 ) / 2

LCD(1342, 20) = 26840 / 2

LCD(1342, 20) = 13420

LCD of 61,22,20 is 13420
