Find LCM of 295,638,420,857,580 with Prime Factorization
| 2 | 295, 638, 420, 857, 580 |
| 2 | 295, 319, 210, 857, 290 |
| 5 | 295, 319, 105, 857, 145 |
| 29 | 59, 319, 21, 857, 29 |
| 59, 11, 21, 857, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 29 x 59 x 11 x 21 x 857 x 1 = 6774430740
Therefore, the lowest common multiple of 295,638,420,857,580 is 6774430740.
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.
295 x 638 x 420 x 857 x 580 = 39291698292000
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.
295 : 1, 5, 59, 295
638 : 1, 2, 11, 22, 29, 58, 319, 638
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
857 : 1, 857
580 : 1, 2, 4, 5, 10, 20, 29, 58, 116, 145, 290, 580
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 295,638,420,857,580, is 1.
Now, the common factors can be found like this.
295:5x 59
638:2x 11x 29
420:2x 2x 3x 5x 7
857:857
580:2x 2x 5x 29
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 5x 5x 29 = 5800
Therefore, the value for common factors is 5800.
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 = 39291698292000/(1x5800)
LCM = 39291698292000/5800
LCM = 6774430740
Thus, we can understand that the LCM of 295,638,420,857,580 is 6774430740.
