Find LCM of 648,186,992,387 with Prime Factorization
| 2 | 648, 186, 992, 387 |
| 2 | 324, 93, 496, 387 |
| 2 | 162, 93, 248, 387 |
| 3 | 81, 93, 124, 387 |
| 3 | 27, 31, 124, 129 |
| 31 | 9, 31, 124, 43 |
| 9, 1, 4, 43 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 3 x 31 x 9 x 1 x 4 x 43 = 3455136
Therefore, the lowest common multiple of 648,186,992,387 is 3455136.
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.
648 x 186 x 992 x 387 = 46271181312
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.
648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648
186 : 1, 2, 3, 6, 31, 62, 93, 186
992 : 1, 2, 4, 8, 16, 31, 32, 62, 124, 248, 496, 992
387 : 1, 3, 9, 43, 129, 387
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 648,186,992,387, is 1.
Now, the common factors can be found like this.
648:2x 2x 2x 3x 3x 3x 3
186:2x 3x 31
992:2x 2x 2x 2x 2x 31
387:3x 3x 43
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 3x 3x 31 = 13392
Therefore, the value for common factors is 13392.
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 = 46271181312/(1x13392)
LCM = 46271181312/13392
LCM = 3455136
Thus, we can understand that the LCM of 648,186,992,387 is 3455136.
