Given numbers are 815,335,628,804,644
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 815,335,628,804,644 is 16563007020.
Find LCM of 815,335,628,804,644 with Prime Factorization
| 2 | 815, 335, 628, 804, 644 |
| 2 | 815, 335, 314, 402, 322 |
| 5 | 815, 335, 157, 201, 161 |
| 67 | 163, 67, 157, 201, 161 |
| 163, 1, 157, 3, 161 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 67 x 163 x 1 x 157 x 3 x 161 = 16563007020
Therefore, the lowest common multiple of 815,335,628,804,644 is 16563007020.
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.
815 x 335 x 628 x 804 x 644 = 88777717627200
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.
815 : 1, 5, 163, 815
335 : 1, 5, 67, 335
628 : 1, 2, 4, 157, 314, 628
804 : 1, 2, 3, 4, 6, 12, 67, 134, 201, 268, 402, 804
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 815,335,628,804,644, is 1.
Now, the common factors can be found like this.
815:5x 163
335:5x 67
628:2x 2x 157
804:2x 2x 3x 67
644:2x 2x 7x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 2x 5x 67 = 5360
Therefore, the value for common factors is 5360.
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 = 88777717627200/(1x5360)
LCM = 88777717627200/5360
LCM = 16563007020
Thus, we can understand that the LCM of 815,335,628,804,644 is 16563007020.
