How to Find LCD of 895,705,456 ?

Given numbers are 895,705,456

We can find the LCD of numbers 895,705,456 by the prime factorization method or by applying the LCD formula.

The LCD of 895,705,456 is 19181640.

Method to Find Least Common Denominator of 895,705,456 with Prime Factorization

3	895, 705, 456
5	895, 235, 152
	179, 47, 152

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 5 x 179 x 47 x 152 = 19181640

Thus, we have determined that the LCD of 895,705,456 is 19181640

LCD Formula to Find LCD of 895,705,456

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

Step1:

Find the GCF of 895 and 705. To find the GCF, list down the factors of 895 and 705 and select the highest factor that appears in both lists of factors.

895 : [1, 5, 179, 895]

705 : [1, 3, 5, 15, 47, 141, 235, 705]

From this, we can see that the GCF of 895 and 705 is 5.

Now, put this into the LCD formula.

LCD(895, 705) = ( 895 x 705 ) / 5

LCD(895, 705) = 630975 / 5

LCD(895, 705) = 126195

Step2:

Find the GCF of 126195 and 456. To find the GCF, list down the factors of 126195 and 456 and select the highest factor that appears in both lists of factors.

126195 : [1, 3, 5, 15, 47, 141, 179, 235, 537, 705, 895, 2685, 8413, 25239, 42065, 126195]

456 : [1, 2, 3, 4, 6, 8, 12, 19, 24, 38, 57, 76, 114, 152, 228, 456]

From this, we can see that the GCF of 126195 and 456 is 3.

Now, put this into the LCD formula.

LCD(126195, 456) = ( 126195 x 456 ) / 3

LCD(126195, 456) = 57544920 / 3

LCD(126195, 456) = 19181640

LCD of 895,705,456 is 19181640
