Given numbers are 774,489,708,449,840
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 774,489,708,449,840 is 467902055880.
Find LCM of 774,489,708,449,840 with Prime Factorization
| 2 | 774, 489, 708, 449, 840 |
| 2 | 387, 489, 354, 449, 420 |
| 3 | 387, 489, 177, 449, 210 |
| 129, 163, 59, 449, 70 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 129 x 163 x 59 x 449 x 70 = 467902055880
Therefore, the lowest common multiple of 774,489,708,449,840 is 467902055880.
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.
774 x 489 x 708 x 449 x 840 = 101066844070080
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.
774 : 1, 2, 3, 6, 9, 18, 43, 86, 129, 258, 387, 774
489 : 1, 3, 163, 489
708 : 1, 2, 3, 4, 6, 12, 59, 118, 177, 236, 354, 708
449 : 1, 449
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 774,489,708,449,840, is 1.
Now, the common factors can be found like this.
774:2x 3x 3x 43
489:3x 163
708:2x 2x 3x 59
449:449
840:2x 2x 2x 3x 5x 7
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 3x 3x 3 = 216
Therefore, the value for common factors is 216.
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 = 101066844070080/(1x216)
LCM = 101066844070080/216
LCM = 467902055880
Thus, we can understand that the LCM of 774,489,708,449,840 is 467902055880.
