Given numbers are 309,683,646,450,920
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 309,683,646,450,920 is 940720897800.
Find LCM of 309,683,646,450,920 with Prime Factorization
| 2 | 309, 683, 646, 450, 920 |
| 3 | 309, 683, 323, 225, 460 |
| 5 | 103, 683, 323, 75, 460 |
| 103, 683, 323, 15, 92 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 103 x 683 x 323 x 15 x 92 = 940720897800
Therefore, the lowest common multiple of 309,683,646,450,920 is 940720897800.
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.
309 x 683 x 646 x 450 x 920 = 56443253868000
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.
309 : 1, 3, 103, 309
683 : 1, 683
646 : 1, 2, 17, 19, 34, 38, 323, 646
450 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 25, 30, 45, 50, 75, 90, 150, 225, 450
920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 309,683,646,450,920, is 1.
Now, the common factors can be found like this.
309:3x 103
683:683
646:2x 17x 19
450:2x 3x 3x 5x 5
920:2x 2x 2x 5x 23
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 3x 5 = 60
Therefore, the value for common factors is 60.
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 = 56443253868000/(1x60)
LCM = 56443253868000/60
LCM = 940720897800
Thus, we can understand that the LCM of 309,683,646,450,920 is 940720897800.
