Given numbers are 489,847,168,755,725
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 489,847,168,755,725 is 362741471400.
Find LCM of 489,847,168,755,725 with Prime Factorization
| 3 | 489, 847, 168, 755, 725 |
| 5 | 163, 847, 56, 755, 725 |
| 7 | 163, 847, 56, 151, 145 |
| 163, 121, 8, 151, 145 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 7 x 163 x 121 x 8 x 151 x 145 = 362741471400
Therefore, the lowest common multiple of 489,847,168,755,725 is 362741471400.
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.
489 x 847 x 168 x 755 x 725 = 38087854497000
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.
489 : 1, 3, 163, 489
847 : 1, 7, 11, 77, 121, 847
168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168
755 : 1, 5, 151, 755
725 : 1, 5, 25, 29, 145, 725
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 489,847,168,755,725, is 1.
Now, the common factors can be found like this.
489:3x 163
847:7x 11x 11
168:2x 2x 2x 3x 7
755:5x 151
725:5x 5x 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 5x 7 = 105
Therefore, the value for common factors is 105.
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 = 38087854497000/(1x105)
LCM = 38087854497000/105
LCM = 362741471400
Thus, we can understand that the LCM of 489,847,168,755,725 is 362741471400.
