Given numbers are 850,139,945,680,289
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 850,139,945,680,289 is 1518463800.
Find LCM of 850,139,945,680,289 with Prime Factorization
| 2 | 850, 139, 945, 680, 289 |
| 5 | 425, 139, 945, 340, 289 |
| 17 | 85, 139, 189, 68, 289 |
| 5, 139, 189, 4, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 17 x 5 x 139 x 189 x 4 x 17 = 1518463800
Therefore, the lowest common multiple of 850,139,945,680,289 is 1518463800.
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.
850 x 139 x 945 x 680 x 289 = 21941801910000
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.
850 : 1, 2, 5, 10, 17, 25, 34, 50, 85, 170, 425, 850
139 : 1, 139
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
289 : 1, 17, 289
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 850,139,945,680,289, is 1.
Now, the common factors can be found like this.
850:2x 5x 5x 17
139:139
945:3x 3x 3x 5x 7
680:2x 2x 2x 5x 17
289:17x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 5x 17x 17 = 14450
Therefore, the value for common factors is 14450.
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 = 21941801910000/(1x14450)
LCM = 21941801910000/14450
LCM = 1518463800
Thus, we can understand that the LCM of 850,139,945,680,289 is 1518463800.
