## How to Find LCD of 29,32,21 ?

Given numbers are 29,32,21

We can find the LCD of numbers 29,32,21 by the prime factorization method or by applying the LCD formula.

The LCD of 29,32,21 is 19488.

##### Method to Find Least Common Denominator of 29,32,21 with Prime Factorization

Given numbers has no common factors except 1. So, there LCD is their product i.e 19488

### LCD Formula to Find LCD of 29,32,21

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

Step1:

Find the GCF of 29 and 32. To find the GCF, list down the factors of 29 and 32 and select the highest factor that appears in both lists of factors.

29 : [1, 29]

32 : [1, 2, 4, 8, 16, 32]

From this, we can see that the GCF of 29 and 32 is 1.

Now, put this into the LCD formula.

LCD(29, 32) = ( 29 x 32 ) / 1

LCD(29, 32) = 928 / 1

LCD(29, 32) = 928

Step2:

Find the GCF of 928 and 21. To find the GCF, list down the factors of 928 and 21 and select the highest factor that appears in both lists of factors.

928 : [1, 2, 4, 8, 16, 29, 32, 58, 116, 232, 464, 928]

21 : [1, 3, 7, 21]

From this, we can see that the GCF of 928 and 21 is 1.

Now, put this into the LCD formula.

LCD(928, 21) = ( 928 x 21 ) / 1

LCD(928, 21) = 19488 / 1

LCD(928, 21) = 19488

LCD of 29,32,21 is 19488
