Given numbers are 705,289,993,670,425
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 705,289,993,670,425 is 45184528650.
Find LCM of 705,289,993,670,425 with Prime Factorization
| 3 | 705, 289, 993, 670, 425 |
| 5 | 235, 289, 331, 670, 425 |
| 17 | 47, 289, 331, 134, 85 |
| 47, 17, 331, 134, 5 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 17 x 47 x 17 x 331 x 134 x 5 = 45184528650
Therefore, the lowest common multiple of 705,289,993,670,425 is 45184528650.
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.
705 x 289 x 993 x 670 x 425 = 57610274028750
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.
705 : 1, 3, 5, 15, 47, 141, 235, 705
289 : 1, 17, 289
993 : 1, 3, 331, 993
670 : 1, 2, 5, 10, 67, 134, 335, 670
425 : 1, 5, 17, 25, 85, 425
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 705,289,993,670,425, is 1.
Now, the common factors can be found like this.
705:3x 5x 47
289:17x 17
993:3x 331
670:2x 5x 67
425:5x 5x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 5x 17 = 1275
Therefore, the value for common factors is 1275.
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 = 57610274028750/(1x1275)
LCM = 57610274028750/1275
LCM = 45184528650
Thus, we can understand that the LCM of 705,289,993,670,425 is 45184528650.
