Find LCM of 369,381,423,768,812 with Prime Factorization
| 2 | 369, 381, 423, 768, 812 |
| 2 | 369, 381, 423, 384, 406 |
| 3 | 369, 381, 423, 192, 203 |
| 3 | 123, 127, 141, 64, 203 |
| 41, 127, 47, 64, 203 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 41 x 127 x 47 x 64 x 203 = 114462690048
Therefore, the lowest common multiple of 369,381,423,768,812 is 114462690048.
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.
369 x 381 x 423 x 768 x 812 = 37085911575552
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.
369 : 1, 3, 9, 41, 123, 369
381 : 1, 3, 127, 381
423 : 1, 3, 9, 47, 141, 423
768 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 256, 384, 768
812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 369,381,423,768,812, is 1.
Now, the common factors can be found like this.
369:3x 3x 41
381:3x 127
423:3x 3x 47
768:2x 2x 2x 2x 2x 2x 2x 2x 3
812:2x 2x 7x 29
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 3x 3x 3x 3 = 324
Therefore, the value for common factors is 324.
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 = 37085911575552/(1x324)
LCM = 37085911575552/324
LCM = 114462690048
Thus, we can understand that the LCM of 369,381,423,768,812 is 114462690048.
