Given numbers are 305,902,768,984
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 305,902,768,984 is 105642240.
Find LCM of 305,902,768,984 with Prime Factorization
| 2 | 305, 902, 768, 984 |
| 2 | 305, 451, 384, 492 |
| 2 | 305, 451, 192, 246 |
| 3 | 305, 451, 96, 123 |
| 41 | 305, 451, 32, 41 |
| 305, 11, 32, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 41 x 305 x 11 x 32 x 1 = 105642240
Therefore, the lowest common multiple of 305,902,768,984 is 105642240.
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.
305 x 902 x 768 x 984 = 207903928320
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.
305 : 1, 5, 61, 305
902 : 1, 2, 11, 22, 41, 82, 451, 902
768 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 256, 384, 768
984 : 1, 2, 3, 4, 6, 8, 12, 24, 41, 82, 123, 164, 246, 328, 492, 984
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 305,902,768,984, is 1.
Now, the common factors can be found like this.
305:5x 61
902:2x 11x 41
768:2x 2x 2x 2x 2x 2x 2x 2x 3
984:2x 2x 2x 3x 41
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 2x 3x 41 = 1968
Therefore, the value for common factors is 1968.
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 = 207903928320/(1x1968)
LCM = 207903928320/1968
LCM = 105642240
Thus, we can understand that the LCM of 305,902,768,984 is 105642240.
