Find LCM of 390,667,738,663,899 with Prime Factorization
| 2 | 390, 667, 738, 663, 899 |
| 3 | 195, 667, 369, 663, 899 |
| 13 | 65, 667, 123, 221, 899 |
| 29 | 5, 667, 123, 17, 899 |
| 5, 23, 123, 17, 31 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 29 x 5 x 23 x 123 x 17 x 31 = 16861886730
Therefore, the lowest common multiple of 390,667,738,663,899 is 16861886730.
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 667 x 738 x 663 x 899 = 114424763349780
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
667 : 1, 23, 29, 667
738 : 1, 2, 3, 6, 9, 18, 41, 82, 123, 246, 369, 738
663 : 1, 3, 13, 17, 39, 51, 221, 663
899 : 1, 29, 31, 899
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 390,667,738,663,899, is 1.
Now, the common factors can be found like this.
390:2x 3x 5x 13
667:23x 29
738:2x 3x 3x 41
663:3x 13x 17
899:29x 31
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 13x 29 = 6786
Therefore, the value for common factors is 6786.
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 = 114424763349780/(1x6786)
LCM = 114424763349780/6786
LCM = 16861886730
Thus, we can understand that the LCM of 390,667,738,663,899 is 16861886730.
