Given numbers are 164,640,218,424,782
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 164,640,218,424,782 is 59271095680.
Find LCM of 164,640,218,424,782 with Prime Factorization
| 2 | 164, 640, 218, 424, 782 |
| 2 | 82, 320, 109, 212, 391 |
| 2 | 41, 160, 109, 106, 391 |
| 41, 80, 109, 53, 391 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 41 x 80 x 109 x 53 x 391 = 59271095680
Therefore, the lowest common multiple of 164,640,218,424,782 is 59271095680.
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.
164 x 640 x 218 x 424 x 782 = 7586700247040
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.
164 : 1, 2, 4, 41, 82, 164
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
218 : 1, 2, 109, 218
424 : 1, 2, 4, 8, 53, 106, 212, 424
782 : 1, 2, 17, 23, 34, 46, 391, 782
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 164,640,218,424,782, is 2.
Now, the common factors can be found like this.
164:2x 2x 41
640:2x 2x 2x 2x 2x 2x 2x 5
218:2x 109
424:2x 2x 2x 53
782:2x 17x 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 2x 2x 2x 2 = 64
Therefore, the value for common factors is 64.
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 = 7586700247040/(2x64)
LCM = 7586700247040/128
LCM = 59271095680
Thus, we can understand that the LCM of 164,640,218,424,782 is 59271095680.
