Find LCM of 552,138,768,943 with Prime Factorization
| 2 | 552, 138, 768, 943 |
| 2 | 276, 69, 384, 943 |
| 2 | 138, 69, 192, 943 |
| 3 | 69, 69, 96, 943 |
| 23 | 23, 23, 32, 943 |
| 1, 1, 32, 41 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 23 x 1 x 1 x 32 x 41 = 724224
Therefore, the lowest common multiple of 552,138,768,943 is 724224.
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.
552 x 138 x 768 x 943 = 55168487424
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.
552 : 1, 2, 3, 4, 6, 8, 12, 23, 24, 46, 69, 92, 138, 184, 276, 552
138 : 1, 2, 3, 6, 23, 46, 69, 138
768 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 256, 384, 768
943 : 1, 23, 41, 943
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 552,138,768,943, is 1.
Now, the common factors can be found like this.
552:2x 2x 2x 3x 23
138:2x 3x 23
768:2x 2x 2x 2x 2x 2x 2x 2x 3
943:23x 41
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 23x 23 = 76176
Therefore, the value for common factors is 76176.
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 = 55168487424/(1x76176)
LCM = 55168487424/76176
LCM = 724224
Thus, we can understand that the LCM of 552,138,768,943 is 724224.
