Given numbers are 315,217,998,670
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 315,217,998,670 is 652946490.
Find LCM of 315,217,998,670 with Prime Factorization
| 2 | 315, 217, 998, 670 |
| 5 | 315, 217, 499, 335 |
| 7 | 63, 217, 499, 67 |
| 9, 31, 499, 67 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 9 x 31 x 499 x 67 = 652946490
Therefore, the lowest common multiple of 315,217,998,670 is 652946490.
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.
315 x 217 x 998 x 670 = 45706254300
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.
315 : 1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, 315
217 : 1, 7, 31, 217
998 : 1, 2, 499, 998
670 : 1, 2, 5, 10, 67, 134, 335, 670
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 315,217,998,670, is 1.
Now, the common factors can be found like this.
315:3x 3x 5x 7
217:7x 31
998:2x 499
670:2x 5x 67
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 7 = 70
Therefore, the value for common factors is 70.
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 = 45706254300/(1x70)
LCM = 45706254300/70
LCM = 652946490
Thus, we can understand that the LCM of 315,217,998,670 is 652946490.
