Given numbers are 643,323,327,228,786
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 643,323,327,228,786 is 35587094772.
Find LCM of 643,323,327,228,786 with Prime Factorization
| 2 | 643, 323, 327, 228, 786 |
| 3 | 643, 323, 327, 114, 393 |
| 19 | 643, 323, 109, 38, 131 |
| 643, 17, 109, 2, 131 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 19 x 643 x 17 x 109 x 2 x 131 = 35587094772
Therefore, the lowest common multiple of 643,323,327,228,786 is 35587094772.
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.
643 x 323 x 327 x 228 x 786 = 12170786412024
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.
643 : 1, 643
323 : 1, 17, 19, 323
327 : 1, 3, 109, 327
228 : 1, 2, 3, 4, 6, 12, 19, 38, 57, 76, 114, 228
786 : 1, 2, 3, 6, 131, 262, 393, 786
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 643,323,327,228,786, is 1.
Now, the common factors can be found like this.
643:643
323:17x 19
327:3x 109
228:2x 2x 3x 19
786:2x 3x 131
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 3x 19 = 342
Therefore, the value for common factors is 342.
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 = 12170786412024/(1x342)
LCM = 12170786412024/342
LCM = 35587094772
Thus, we can understand that the LCM of 643,323,327,228,786 is 35587094772.
