Given numbers are 269,105,940,642
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 269,105,940,642 is 568176420.
Find LCM of 269,105,940,642 with Prime Factorization
| 2 | 269, 105, 940, 642 |
| 3 | 269, 105, 470, 321 |
| 5 | 269, 35, 470, 107 |
| 269, 7, 94, 107 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 269 x 7 x 94 x 107 = 568176420
Therefore, the lowest common multiple of 269,105,940,642 is 568176420.
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.
269 x 105 x 940 x 642 = 17045292600
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.
269 : 1, 269
105 : 1, 3, 5, 7, 15, 21, 35, 105
940 : 1, 2, 4, 5, 10, 20, 47, 94, 188, 235, 470, 940
642 : 1, 2, 3, 6, 107, 214, 321, 642
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 269,105,940,642, is 1.
Now, the common factors can be found like this.
269:269
105:3x 5x 7
940:2x 2x 5x 47
642:2x 3x 107
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 5 = 30
Therefore, the value for common factors is 30.
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 = 17045292600/(1x30)
LCM = 17045292600/30
LCM = 568176420
Thus, we can understand that the LCM of 269,105,940,642 is 568176420.
