Given numbers are 391,863,143,489,624
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 391,863,143,489,624 is 377530838256.
Find LCM of 391,863,143,489,624 with Prime Factorization
| 3 | 391, 863, 143, 489, 624 |
| 13 | 391, 863, 143, 163, 208 |
| 391, 863, 11, 163, 16 |
Multiply the prime numbers at the bottom and the left side.
3 x 13 x 391 x 863 x 11 x 163 x 16 = 377530838256
Therefore, the lowest common multiple of 391,863,143,489,624 is 377530838256.
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 863 x 143 x 489 x 624 = 14723702691984
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
863 : 1, 863
143 : 1, 11, 13, 143
489 : 1, 3, 163, 489
624 : 1, 2, 3, 4, 6, 8, 12, 13, 16, 24, 26, 39, 48, 52, 78, 104, 156, 208, 312, 624
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 391,863,143,489,624, is 1.
Now, the common factors can be found like this.
391:17x 23
863:863
143:11x 13
489:3x 163
624:2x 2x 2x 2x 3x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 13 = 39
Therefore, the value for common factors is 39.
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 = 14723702691984/(1x39)
LCM = 14723702691984/39
LCM = 377530838256
Thus, we can understand that the LCM of 391,863,143,489,624 is 377530838256.
