The LCM of 864,667,315,938 is 1351395360.
Find LCM of 864,667,315,938 with Prime Factorization
| 2 | 864, 667, 315, 938 |
| 3 | 432, 667, 315, 469 |
| 3 | 144, 667, 105, 469 |
| 7 | 48, 667, 35, 469 |
| 48, 667, 5, 67 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 7 x 48 x 667 x 5 x 67 = 1351395360
Therefore, the lowest common multiple of 864,667,315,938 is 1351395360.
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.
864 x 667 x 315 x 938 = 170275815360
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.
864 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 32, 36, 48, 54, 72, 96, 108, 144, 216, 288, 432, 864
667 : 1, 23, 29, 667
315 : 1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, 315
938 : 1, 2, 7, 14, 67, 134, 469, 938
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 864,667,315,938, is 1.
Now, the common factors can be found like this.
864:2x 2x 2x 2x 2x 3x 3x 3
667:23x 29
315:3x 3x 5x 7
938:2x 7x 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 3x 3x 7 = 126
Therefore, the value for common factors is 126.
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 = 170275815360/(1x126)
LCM = 170275815360/126
LCM = 1351395360
Thus, we can understand that the LCM of 864,667,315,938 is 1351395360.
