Given numbers are 649,121,449,916,828
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 649,121,449,916,828 is 607784390532.
Find LCM of 649,121,449,916,828 with Prime Factorization
| 2 | 649, 121, 449, 916, 828 |
| 2 | 649, 121, 449, 458, 414 |
| 11 | 649, 121, 449, 229, 207 |
| 59, 11, 449, 229, 207 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 59 x 11 x 449 x 229 x 207 = 607784390532
Therefore, the lowest common multiple of 649,121,449,916,828 is 607784390532.
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.
649 x 121 x 449 x 916 x 828 = 26742513183408
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.
649 : 1, 11, 59, 649
121 : 1, 11, 121
449 : 1, 449
916 : 1, 2, 4, 229, 458, 916
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 649,121,449,916,828, is 1.
Now, the common factors can be found like this.
649:11x 59
121:11x 11
449:449
916:2x 2x 229
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 11 = 44
Therefore, the value for common factors is 44.
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 = 26742513183408/(1x44)
LCM = 26742513183408/44
LCM = 607784390532
Thus, we can understand that the LCM of 649,121,449,916,828 is 607784390532.
