Find LCM of 305,633,976,128,781 with Prime Factorization
| 2 | 305, 633, 976, 128, 781 |
| 2 | 305, 633, 488, 64, 781 |
| 2 | 305, 633, 244, 32, 781 |
| 2 | 305, 633, 122, 16, 781 |
| 61 | 305, 633, 61, 8, 781 |
| 5, 633, 1, 8, 781 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 61 x 5 x 633 x 1 x 8 x 781 = 19300321920
Therefore, the lowest common multiple of 305,633,976,128,781 is 19300321920.
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 633 x 976 x 128 x 781 = 18837114193920
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
633 : 1, 3, 211, 633
976 : 1, 2, 4, 8, 16, 61, 122, 244, 488, 976
128 : 1, 2, 4, 8, 16, 32, 64, 128
781 : 1, 11, 71, 781
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 305,633,976,128,781, is 1.
Now, the common factors can be found like this.
305:5x 61
633:3x 211
976:2x 2x 2x 2x 61
128:2x 2x 2x 2x 2x 2x 2
781:11x 71
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 61 = 976
Therefore, the value for common factors is 976.
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 = 18837114193920/(1x976)
LCM = 18837114193920/976
LCM = 19300321920
Thus, we can understand that the LCM of 305,633,976,128,781 is 19300321920.
