Find LCM of 956,923,438,780,861 with Prime Factorization
| 2 | 956, 923, 438, 780, 861 |
| 2 | 478, 923, 219, 390, 861 |
| 3 | 239, 923, 219, 195, 861 |
| 13 | 239, 923, 73, 65, 287 |
| 239, 71, 73, 5, 287 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 13 x 239 x 71 x 73 x 5 x 287 = 277303664820
Therefore, the lowest common multiple of 956,923,438,780,861 is 277303664820.
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.
956 x 923 x 438 x 780 x 861 = 259556230271520
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.
956 : 1, 2, 4, 239, 478, 956
923 : 1, 13, 71, 923
438 : 1, 2, 3, 6, 73, 146, 219, 438
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
861 : 1, 3, 7, 21, 41, 123, 287, 861
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 956,923,438,780,861, is 1.
Now, the common factors can be found like this.
956:2x 2x 239
923:13x 71
438:2x 3x 73
780:2x 2x 3x 5x 13
861:3x 7x 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 3x 3x 13 = 936
Therefore, the value for common factors is 936.
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 = 259556230271520/(1x936)
LCM = 259556230271520/936
LCM = 277303664820
Thus, we can understand that the LCM of 956,923,438,780,861 is 277303664820.
