Given numbers are 390,908,437,894
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 390,908,437,894 is 11528907780.
Find LCM of 390,908,437,894 with Prime Factorization
| 2 | 390, 908, 437, 894 |
| 3 | 195, 454, 437, 447 |
| 65, 454, 437, 149 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 65 x 454 x 437 x 149 = 11528907780
Therefore, the lowest common multiple of 390,908,437,894 is 11528907780.
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 908 x 437 x 894 = 138346893360
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
908 : 1, 2, 4, 227, 454, 908
437 : 1, 19, 23, 437
894 : 1, 2, 3, 6, 149, 298, 447, 894
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 390,908,437,894, is 1.
Now, the common factors can be found like this.
390:2x 3x 5x 13
908:2x 2x 227
437:19x 23
894:2x 3x 149
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 3 = 12
Therefore, the value for common factors is 12.
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 = 138346893360/(1x12)
LCM = 138346893360/12
LCM = 11528907780
Thus, we can understand that the LCM of 390,908,437,894 is 11528907780.
