Find LCM of 128,767,668,885,936 with Prime Factorization
| 2 | 128, 767, 668, 885, 936 |
| 2 | 64, 767, 334, 885, 468 |
| 2 | 32, 767, 167, 885, 234 |
| 3 | 16, 767, 167, 885, 117 |
| 13 | 16, 767, 167, 295, 39 |
| 59 | 16, 59, 167, 295, 3 |
| 16, 1, 167, 5, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 13 x 59 x 16 x 1 x 167 x 5 x 3 = 737792640
Therefore, the lowest common multiple of 128,767,668,885,936 is 737792640.
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.
128 x 767 x 668 x 885 x 936 = 54325147668480
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.
128 : 1, 2, 4, 8, 16, 32, 64, 128
767 : 1, 13, 59, 767
668 : 1, 2, 4, 167, 334, 668
885 : 1, 3, 5, 15, 59, 177, 295, 885
936 : 1, 2, 3, 4, 6, 8, 9, 12, 13, 18, 24, 26, 36, 39, 52, 72, 78, 104, 117, 156, 234, 312, 468, 936
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 128,767,668,885,936, is 1.
Now, the common factors can be found like this.
128:2x 2x 2x 2x 2x 2x 2
767:13x 59
668:2x 2x 167
885:3x 5x 59
936:2x 2x 2x 3x 3x 13
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 2x 3x 13x 59 = 73632
Therefore, the value for common factors is 73632.
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 = 54325147668480/(1x73632)
LCM = 54325147668480/73632
LCM = 737792640
Thus, we can understand that the LCM of 128,767,668,885,936 is 737792640.
