Given numbers are 655,820,802,328
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 655,820,802,328 is 86150840.
Find LCM of 655,820,802,328 with Prime Factorization
| 2 | 655, 820, 802, 328 |
| 2 | 655, 410, 401, 164 |
| 5 | 655, 205, 401, 82 |
| 41 | 131, 41, 401, 82 |
| 131, 1, 401, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 41 x 131 x 1 x 401 x 2 = 86150840
Therefore, the lowest common multiple of 655,820,802,328 is 86150840.
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.
655 x 820 x 802 x 328 = 141287377600
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.
655 : 1, 5, 131, 655
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
802 : 1, 2, 401, 802
328 : 1, 2, 4, 8, 41, 82, 164, 328
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 655,820,802,328, is 1.
Now, the common factors can be found like this.
655:5x 131
820:2x 2x 5x 41
802:2x 401
328:2x 2x 2x 41
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 5x 41 = 1640
Therefore, the value for common factors is 1640.
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 = 141287377600/(1x1640)
LCM = 141287377600/1640
LCM = 86150840
Thus, we can understand that the LCM of 655,820,802,328 is 86150840.
