Find LCM of 418,781,330,738,432 with Prime Factorization
| 2 | 418, 781, 330, 738, 432 |
| 3 | 209, 781, 165, 369, 216 |
| 3 | 209, 781, 55, 123, 72 |
| 11 | 209, 781, 55, 41, 24 |
| 19, 71, 5, 41, 24 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 11 x 19 x 71 x 5 x 41 x 24 = 1314141840
Therefore, the lowest common multiple of 418,781,330,738,432 is 1314141840.
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.
418 x 781 x 330 x 738 x 432 = 34346411130240
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.
418 : 1, 2, 11, 19, 22, 38, 209, 418
781 : 1, 11, 71, 781
330 : 1, 2, 3, 5, 6, 10, 11, 15, 22, 30, 33, 55, 66, 110, 165, 330
738 : 1, 2, 3, 6, 9, 18, 41, 82, 123, 246, 369, 738
432 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 36, 48, 54, 72, 108, 144, 216, 432
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 418,781,330,738,432, is 1.
Now, the common factors can be found like this.
418:2x 11x 19
781:11x 71
330:2x 3x 5x 11
738:2x 3x 3x 41
432:2x 2x 2x 2x 3x 3x 3
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 3x 3x 3x 11x 11 = 26136
Therefore, the value for common factors is 26136.
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 = 34346411130240/(1x26136)
LCM = 34346411130240/26136
LCM = 1314141840
Thus, we can understand that the LCM of 418,781,330,738,432 is 1314141840.
