Find LCM of 576,384,520,978 with Prime Factorization
| 2 | 576, 384, 520, 978 |
| 2 | 288, 192, 260, 489 |
| 2 | 144, 96, 130, 489 |
| 2 | 72, 48, 65, 489 |
| 2 | 36, 24, 65, 489 |
| 2 | 18, 12, 65, 489 |
| 3 | 9, 6, 65, 489 |
| 3, 2, 65, 163 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 2 x 2 x 3 x 3 x 2 x 65 x 163 = 12205440
Therefore, the lowest common multiple of 576,384,520,978 is 12205440.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
576 x 384 x 520 x 978 = 112485335040
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
576 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 32, 36, 48, 64, 72, 96, 144, 192, 288, 576
384 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 384
520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520
978 : 1, 2, 3, 6, 163, 326, 489, 978
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 576,384,520,978, is 2.
Now, the common factors can be found like this.
576:2x 2x 2x 2x 2x 2x 3x 3
384:2x 2x 2x 2x 2x 2x 2x 3
520:2x 2x 2x 5x 13
978:2x 3x 163
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 2x 2x 2x 2x 2x 2x 3x 3 = 4608
Therefore, the value for common factors is 4608.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 112485335040/(2x4608)
LCM = 112485335040/9216
LCM = 12205440
Thus, we can understand that the LCM of 576,384,520,978 is 12205440.
