Given numbers are 463,618,717,840
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 463,618,717,840 is 9574043640.
Find LCM of 463,618,717,840 with Prime Factorization
| 2 | 463, 618, 717, 840 |
| 3 | 463, 309, 717, 420 |
| 463, 103, 239, 140 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 463 x 103 x 239 x 140 = 9574043640
Therefore, the lowest common multiple of 463,618,717,840 is 9574043640.
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.
463 x 618 x 717 x 840 = 172332785520
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.
463 : 1, 463
618 : 1, 2, 3, 6, 103, 206, 309, 618
717 : 1, 3, 239, 717
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 463,618,717,840, is 1.
Now, the common factors can be found like this.
463:463
618:2x 3x 103
717:3x 239
840:2x 2x 2x 3x 5x 7
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 3 = 18
Therefore, the value for common factors is 18.
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 = 172332785520/(1x18)
LCM = 172332785520/18
LCM = 9574043640
Thus, we can understand that the LCM of 463,618,717,840 is 9574043640.
