How to Find LCD of 580,999,290 ?

Given numbers are 580,999,290

We can find the LCD of numbers 580,999,290 by the prime factorization method or by applying the LCD formula.

The LCD of 580,999,290 is 579420.


Method to Find Least Common Denominator of 580,999,290 with Prime Factorization

2 580, 999, 290
5 290, 999, 145
29 58, 999, 29
2, 999, 1

As you can see, now we have to multiply the prime numbers on the left side with the co-primes at the bottom.
2 x 5 x 29 x 2 x 999 x 1 = 579420

Thus, we have determined that the LCD of 580,999,290 is 579420

LCD Formula to Find LCD of 580,999,290

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


Step1:

Find the GCF of 580 and 999. To find the GCF, list down the factors of 580 and 999 and select the highest factor that appears in both lists of factors.

580 : [1, 2, 4, 5, 10, 20, 29, 58, 116, 145, 290, 580]

999 : [1, 3, 9, 27, 37, 111, 333, 999]

From this, we can see that the GCF of 580 and 999 is 1.

Now, put this into the LCD formula.

LCD(580, 999) = ( 580 x 999 ) / 1

LCD(580, 999) = 579420 / 1

LCD(580, 999) = 579420


Step2:

Find the GCF of 579420 and 290. To find the GCF, list down the factors of 579420 and 290 and select the highest factor that appears in both lists of factors.

579420 : [1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 27, 29, 30, 36, 37, 45, 54, 58, 60, 74, 87, 90, 108, 111, 116, 135, 145, 148, 174, 180, 185, 222, 261, 270, 290, 333, 348, 370, 435, 444, 522, 540, 555, 580, 666, 740, 783, 870, 999, 1044, 1073, 1110, 1305, 1332, 1566, 1665, 1740, 1998, 2146, 2220, 2610, 3132, 3219, 3330, 3915, 3996, 4292, 4995, 5220, 5365, 6438, 6660, 7830, 9657, 9990, 10730, 12876, 15660, 16095, 19314, 19980, 21460, 28971, 32190, 38628, 48285, 57942, 64380, 96570, 115884, 144855, 193140, 289710, 579420]

290 : [1, 2, 5, 10, 29, 58, 145, 290]

From this, we can see that the GCF of 579420 and 290 is 290.

Now, put this into the LCD formula.

LCD(579420, 290) = ( 579420 x 290 ) / 290

LCD(579420, 290) = 168031800 / 290

LCD(579420, 290) = 579420

LCD of 580,999,290 is 579420
