Given numbers are 421,824,231,718,828
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 421,824,231,718,828 is 1985019725304.
Find LCM of 421,824,231,718,828 with Prime Factorization
| 2 | 421, 824, 231, 718, 828 |
| 2 | 421, 412, 231, 359, 414 |
| 3 | 421, 206, 231, 359, 207 |
| 421, 206, 77, 359, 69 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 421 x 206 x 77 x 359 x 69 = 1985019725304
Therefore, the lowest common multiple of 421,824,231,718,828 is 1985019725304.
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.
421 x 824 x 231 x 718 x 828 = 47640473407296
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.
421 : 1, 421
824 : 1, 2, 4, 8, 103, 206, 412, 824
231 : 1, 3, 7, 11, 21, 33, 77, 231
718 : 1, 2, 359, 718
828 : 1, 2, 3, 4, 6, 9, 12, 18, 23, 36, 46, 69, 92, 138, 207, 276, 414, 828
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 421,824,231,718,828, is 1.
Now, the common factors can be found like this.
421:421
824:2x 2x 2x 103
231:3x 7x 11
718:2x 359
828:2x 2x 3x 3x 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 3 = 24
Therefore, the value for common factors is 24.
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 = 47640473407296/(1x24)
LCM = 47640473407296/24
LCM = 1985019725304
Thus, we can understand that the LCM of 421,824,231,718,828 is 1985019725304.
