Find LCM of 391,575,860,506,823 with Prime Factorization
| 2 | 391, 575, 860, 506, 823 |
| 5 | 391, 575, 430, 253, 823 |
| 23 | 391, 115, 86, 253, 823 |
| 17, 5, 86, 11, 823 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 23 x 17 x 5 x 86 x 11 x 823 = 15220808900
Therefore, the lowest common multiple of 391,575,860,506,823 is 15220808900.
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.
391 x 575 x 860 x 506 x 823 = 80518079081000
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.
391 : 1, 17, 23, 391
575 : 1, 5, 23, 25, 115, 575
860 : 1, 2, 4, 5, 10, 20, 43, 86, 172, 215, 430, 860
506 : 1, 2, 11, 22, 23, 46, 253, 506
823 : 1, 823
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 391,575,860,506,823, is 1.
Now, the common factors can be found like this.
391:17x 23
575:5x 5x 23
860:2x 2x 5x 43
506:2x 11x 23
823:823
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 23x 23 = 5290
Therefore, the value for common factors is 5290.
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 = 80518079081000/(1x5290)
LCM = 80518079081000/5290
LCM = 15220808900
Thus, we can understand that the LCM of 391,575,860,506,823 is 15220808900.
