Find LCM of 717,978,768,714,520 with Prime Factorization
| 2 | 717, 978, 768, 714, 520 |
| 2 | 717, 489, 384, 357, 260 |
| 2 | 717, 489, 192, 357, 130 |
| 3 | 717, 489, 96, 357, 65 |
| 239, 163, 32, 119, 65 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 239 x 163 x 32 x 119 x 65 = 231423279360
Therefore, the lowest common multiple of 717,978,768,714,520 is 231423279360.
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.
717 x 978 x 768 x 714 x 520 = 199949713367040
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.
717 : 1, 3, 239, 717
978 : 1, 2, 3, 6, 163, 326, 489, 978
768 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 256, 384, 768
714 : 1, 2, 3, 6, 7, 14, 17, 21, 34, 42, 51, 102, 119, 238, 357, 714
520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 717,978,768,714,520, is 1.
Now, the common factors can be found like this.
717:3x 239
978:2x 3x 163
768:2x 2x 2x 2x 2x 2x 2x 2x 3
714:2x 3x 7x 17
520:2x 2x 2x 5x 13
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 3x 3x 3 = 864
Therefore, the value for common factors is 864.
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 = 199949713367040/(1x864)
LCM = 199949713367040/864
LCM = 231423279360
Thus, we can understand that the LCM of 717,978,768,714,520 is 231423279360.
