Find LCM of 889,930,431,845,390 with Prime Factorization
| 2 | 889, 930, 431, 845, 390 |
| 3 | 889, 465, 431, 845, 195 |
| 5 | 889, 155, 431, 845, 65 |
| 13 | 889, 31, 431, 169, 13 |
| 889, 31, 431, 1, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 13 x 889 x 31 x 431 x 1 x 13 = 60221100030
Therefore, the lowest common multiple of 889,930,431,845,390 is 60221100030.
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.
889 x 930 x 431 x 845 x 390 = 117431145058500
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.
889 : 1, 7, 127, 889
930 : 1, 2, 3, 5, 6, 10, 15, 30, 31, 62, 93, 155, 186, 310, 465, 930
431 : 1, 431
845 : 1, 5, 13, 65, 169, 845
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 889,930,431,845,390, is 1.
Now, the common factors can be found like this.
889:7x 127
930:2x 3x 5x 31
431:431
845:5x 13x 13
390:2x 3x 5x 13
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 5x 5x 13 = 1950
Therefore, the value for common factors is 1950.
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 = 117431145058500/(1x1950)
LCM = 117431145058500/1950
LCM = 60221100030
Thus, we can understand that the LCM of 889,930,431,845,390 is 60221100030.
