Find LCM of 390,889,340,185,923 with Prime Factorization
| 2 | 390, 889, 340, 185, 923 |
| 5 | 195, 889, 170, 185, 923 |
| 13 | 39, 889, 34, 37, 923 |
| 3, 889, 34, 37, 71 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 13 x 3 x 889 x 34 x 37 x 71 = 30967443780
Therefore, the lowest common multiple of 390,889,340,185,923 is 30967443780.
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.
390 x 889 x 340 x 185 x 923 = 20128838457000
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.
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
889 : 1, 7, 127, 889
340 : 1, 2, 4, 5, 10, 17, 20, 34, 68, 85, 170, 340
185 : 1, 5, 37, 185
923 : 1, 13, 71, 923
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 390,889,340,185,923, is 1.
Now, the common factors can be found like this.
390:2x 3x 5x 13
889:7x 127
340:2x 2x 5x 17
185:5x 37
923:13x 71
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 5x 13 = 650
Therefore, the value for common factors is 650.
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 = 20128838457000/(1x650)
LCM = 20128838457000/650
LCM = 30967443780
Thus, we can understand that the LCM of 390,889,340,185,923 is 30967443780.
