Given numbers are 391,689,474,708,901
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 391,689,474,708,901 is 15068024868.
Find LCM of 391,689,474,708,901 with Prime Factorization
| 2 | 391, 689, 474, 708, 901 |
| 3 | 391, 689, 237, 354, 901 |
| 17 | 391, 689, 79, 118, 901 |
| 53 | 23, 689, 79, 118, 53 |
| 23, 13, 79, 118, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 17 x 53 x 23 x 13 x 79 x 118 x 1 = 15068024868
Therefore, the lowest common multiple of 391,689,474,708,901 is 15068024868.
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 689 x 474 x 708 x 901 = 81457742436408
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
689 : 1, 13, 53, 689
474 : 1, 2, 3, 6, 79, 158, 237, 474
708 : 1, 2, 3, 4, 6, 12, 59, 118, 177, 236, 354, 708
901 : 1, 17, 53, 901
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 391,689,474,708,901, is 1.
Now, the common factors can be found like this.
391:17x 23
689:13x 53
474:2x 3x 79
708:2x 2x 3x 59
901:17x 53
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 17x 53 = 5406
Therefore, the value for common factors is 5406.
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 = 81457742436408/(1x5406)
LCM = 81457742436408/5406
LCM = 15068024868
Thus, we can understand that the LCM of 391,689,474,708,901 is 15068024868.
