How to Find LCD of 766,111,921 ?

Given numbers are 766,111,921

We can find the LCD of numbers 766,111,921 by the prime factorization method or by applying the LCD formula.

The LCD of 766,111,921 is 26102982.


Method to Find Least Common Denominator of 766,111,921 with Prime Factorization

3 766, 111, 921
766, 37, 307

As you can see, now we have to multiply the prime numbers on the left side with the co-primes at the bottom.
3 x 766 x 37 x 307 = 26102982

Thus, we have determined that the LCD of 766,111,921 is 26102982

LCD Formula to Find LCD of 766,111,921

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


Step1:

Find the GCF of 766 and 111. To find the GCF, list down the factors of 766 and 111 and select the highest factor that appears in both lists of factors.

766 : [1, 2, 383, 766]

111 : [1, 3, 37, 111]

From this, we can see that the GCF of 766 and 111 is 1.

Now, put this into the LCD formula.

LCD(766, 111) = ( 766 x 111 ) / 1

LCD(766, 111) = 85026 / 1

LCD(766, 111) = 85026


Step2:

Find the GCF of 85026 and 921. To find the GCF, list down the factors of 85026 and 921 and select the highest factor that appears in both lists of factors.

85026 : [1, 2, 3, 6, 37, 74, 111, 222, 383, 766, 1149, 2298, 14171, 28342, 42513, 85026]

921 : [1, 3, 307, 921]

From this, we can see that the GCF of 85026 and 921 is 3.

Now, put this into the LCD formula.

LCD(85026, 921) = ( 85026 x 921 ) / 3

LCD(85026, 921) = 78308946 / 3

LCD(85026, 921) = 26102982

LCD of 766,111,921 is 26102982
