Given numbers are 640,259,518,579,214
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 640,259,518,579,214 is 10269329280.
Find LCM of 640,259,518,579,214 with Prime Factorization
| 2 | 640, 259, 518, 579, 214 |
| 7 | 320, 259, 259, 579, 107 |
| 37 | 320, 37, 37, 579, 107 |
| 320, 1, 1, 579, 107 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 37 x 320 x 1 x 1 x 579 x 107 = 10269329280
Therefore, the lowest common multiple of 640,259,518,579,214 is 10269329280.
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.
640 x 259 x 518 x 579 x 214 = 10639025134080
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.
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
259 : 1, 7, 37, 259
518 : 1, 2, 7, 14, 37, 74, 259, 518
579 : 1, 3, 193, 579
214 : 1, 2, 107, 214
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 640,259,518,579,214, is 1.
Now, the common factors can be found like this.
640:2x 2x 2x 2x 2x 2x 2x 5
259:7x 37
518:2x 7x 37
579:3x 193
214:2x 107
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 7x 37 = 1036
Therefore, the value for common factors is 1036.
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 = 10639025134080/(1x1036)
LCM = 10639025134080/1036
LCM = 10269329280
Thus, we can understand that the LCM of 640,259,518,579,214 is 10269329280.
