Given numbers are 319,105,861,497
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 319,105,861,497 is 97503945.
Find LCM of 319,105,861,497 with Prime Factorization
| 3 | 319, 105, 861, 497 |
| 7 | 319, 35, 287, 497 |
| 319, 5, 41, 71 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 319 x 5 x 41 x 71 = 97503945
Therefore, the lowest common multiple of 319,105,861,497 is 97503945.
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.
319 x 105 x 861 x 497 = 14333079915
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.
319 : 1, 11, 29, 319
105 : 1, 3, 5, 7, 15, 21, 35, 105
861 : 1, 3, 7, 21, 41, 123, 287, 861
497 : 1, 7, 71, 497
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 319,105,861,497, is 1.
Now, the common factors can be found like this.
319:11x 29
105:3x 5x 7
861:3x 7x 41
497:7x 71
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 7x 7 = 147
Therefore, the value for common factors is 147.
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 = 14333079915/(1x147)
LCM = 14333079915/147
LCM = 97503945
Thus, we can understand that the LCM of 319,105,861,497 is 97503945.
