Given numbers are 684,631,232,705
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 684,631,232,705 is 5882762520.
Find LCM of 684,631,232,705 with Prime Factorization
| 2 | 684, 631, 232, 705 |
| 2 | 342, 631, 116, 705 |
| 3 | 171, 631, 58, 705 |
| 57, 631, 58, 235 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 57 x 631 x 58 x 235 = 5882762520
Therefore, the lowest common multiple of 684,631,232,705 is 5882762520.
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.
684 x 631 x 232 x 705 = 70593150240
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.
684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684
631 : 1, 631
232 : 1, 2, 4, 8, 29, 58, 116, 232
705 : 1, 3, 5, 15, 47, 141, 235, 705
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 684,631,232,705, is 1.
Now, the common factors can be found like this.
684:2x 2x 3x 3x 19
631:631
232:2x 2x 2x 29
705:3x 5x 47
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 3 = 12
Therefore, the value for common factors is 12.
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 = 70593150240/(1x12)
LCM = 70593150240/12
LCM = 5882762520
Thus, we can understand that the LCM of 684,631,232,705 is 5882762520.
