Find LCM of 912,361,791,438,831 with Prime Factorization
| 2 | 912, 361, 791, 438, 831 |
| 3 | 456, 361, 791, 219, 831 |
| 19 | 152, 361, 791, 73, 277 |
| 8, 19, 791, 73, 277 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 19 x 8 x 19 x 791 x 73 x 277 = 277158085008
Therefore, the lowest common multiple of 912,361,791,438,831 is 277158085008.
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.
912 x 361 x 791 x 438 x 831 = 94788065072736
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.
912 : 1, 2, 3, 4, 6, 8, 12, 16, 19, 24, 38, 48, 57, 76, 114, 152, 228, 304, 456, 912
361 : 1, 19, 361
791 : 1, 7, 113, 791
438 : 1, 2, 3, 6, 73, 146, 219, 438
831 : 1, 3, 277, 831
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 912,361,791,438,831, is 1.
Now, the common factors can be found like this.
912:2x 2x 2x 2x 3x 19
361:19x 19
791:7x 113
438:2x 3x 73
831:3x 277
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 19 = 342
Therefore, the value for common factors is 342.
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 = 94788065072736/(1x342)
LCM = 94788065072736/342
LCM = 277158085008
Thus, we can understand that the LCM of 912,361,791,438,831 is 277158085008.
