Find LCM of 578,420,856,833,500 with Prime Factorization
| 2 | 578, 420, 856, 833, 500 |
| 2 | 289, 210, 428, 833, 250 |
| 5 | 289, 105, 214, 833, 125 |
| 7 | 289, 21, 214, 833, 25 |
| 17 | 289, 3, 214, 119, 25 |
| 17, 3, 214, 7, 25 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 7 x 17 x 17 x 3 x 214 x 7 x 25 = 4545681000
Therefore, the lowest common multiple of 578,420,856,833,500 is 4545681000.
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.
578 x 420 x 856 x 833 x 500 = 86549766240000
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.
578 : 1, 2, 17, 34, 289, 578
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
856 : 1, 2, 4, 8, 107, 214, 428, 856
833 : 1, 7, 17, 49, 119, 833
500 : 1, 2, 4, 5, 10, 20, 25, 50, 100, 125, 250, 500
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 578,420,856,833,500, is 1.
Now, the common factors can be found like this.
578:2x 17x 17
420:2x 2x 3x 5x 7
856:2x 2x 2x 107
833:7x 7x 17
500:2x 2x 5x 5x 5
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 5x 7x 17 = 19040
Therefore, the value for common factors is 19040.
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 = 86549766240000/(1x19040)
LCM = 86549766240000/19040
LCM = 4545681000
Thus, we can understand that the LCM of 578,420,856,833,500 is 4545681000.
