Given numbers are 618,780,407,904,383
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 618,780,407,904,383 is 2830306376040.
Find LCM of 618,780,407,904,383 with Prime Factorization
| 2 | 618, 780, 407, 904, 383 |
| 2 | 309, 390, 407, 452, 383 |
| 3 | 309, 195, 407, 226, 383 |
| 103, 65, 407, 226, 383 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 103 x 65 x 407 x 226 x 383 = 2830306376040
Therefore, the lowest common multiple of 618,780,407,904,383 is 2830306376040.
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.
618 x 780 x 407 x 904 x 383 = 67927353024960
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.
618 : 1, 2, 3, 6, 103, 206, 309, 618
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
407 : 1, 11, 37, 407
904 : 1, 2, 4, 8, 113, 226, 452, 904
383 : 1, 383
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 618,780,407,904,383, is 1.
Now, the common factors can be found like this.
618:2x 3x 103
780:2x 2x 3x 5x 13
407:11x 37
904:2x 2x 2x 113
383:383
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 = 67927353024960/(1x24)
LCM = 67927353024960/24
LCM = 2830306376040
Thus, we can understand that the LCM of 618,780,407,904,383 is 2830306376040.
