Given numbers are 654,783,423,203
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 654,783,423,203 is 56158326.
Find LCM of 654,783,423,203 with Prime Factorization
| 3 | 654, 783, 423, 203 |
| 3 | 218, 261, 141, 203 |
| 29 | 218, 87, 47, 203 |
| 218, 3, 47, 7 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 29 x 218 x 3 x 47 x 7 = 56158326
Therefore, the lowest common multiple of 654,783,423,203 is 56158326.
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.
654 x 783 x 423 x 203 = 43971969258
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.
654 : 1, 2, 3, 6, 109, 218, 327, 654
783 : 1, 3, 9, 27, 29, 87, 261, 783
423 : 1, 3, 9, 47, 141, 423
203 : 1, 7, 29, 203
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 654,783,423,203, is 1.
Now, the common factors can be found like this.
654:2x 3x 109
783:3x 3x 3x 29
423:3x 3x 47
203:7x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 29 = 783
Therefore, the value for common factors is 783.
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 = 43971969258/(1x783)
LCM = 43971969258/783
LCM = 56158326
Thus, we can understand that the LCM of 654,783,423,203 is 56158326.
