Given numbers are 643,616,405,537,158
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 643,616,405,537,158 is 2268437565240.
Find LCM of 643,616,405,537,158 with Prime Factorization
2 | 643, 616, 405, 537, 158 |
3 | 643, 308, 405, 537, 79 |
643, 308, 135, 179, 79 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 643 x 308 x 135 x 179 x 79 = 2268437565240
Therefore, the lowest common multiple of 643,616,405,537,158 is 2268437565240.
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 616 x 405 x 537 x 158 = 13610625391440
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
616 : 1, 2, 4, 7, 8, 11, 14, 22, 28, 44, 56, 77, 88, 154, 308, 616
405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405
537 : 1, 3, 179, 537
158 : 1, 2, 79, 158
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 643,616,405,537,158, is 1.
Now, the common factors can be found like this.
643:643
616:2x 2x 2x 7x 11
405:3x 3x 3x 3x 5
537:3x 179
158:2x 79
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3 = 6
Therefore, the value for common factors is 6.
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 = 13610625391440/(1x6)
LCM = 13610625391440/6
LCM = 2268437565240
Thus, we can understand that the LCM of 643,616,405,537,158 is 2268437565240.
