Given numbers are 908,372,780,845
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 908,372,780,845 is 71355180.
Find LCM of 908,372,780,845 with Prime Factorization
| 2 | 908, 372, 780, 845 |
| 2 | 454, 186, 390, 845 |
| 3 | 227, 93, 195, 845 |
| 5 | 227, 31, 65, 845 |
| 13 | 227, 31, 13, 169 |
| 227, 31, 1, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 13 x 227 x 31 x 1 x 13 = 71355180
Therefore, the lowest common multiple of 908,372,780,845 is 71355180.
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.
908 x 372 x 780 x 845 = 222628161600
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.
908 : 1, 2, 4, 227, 454, 908
372 : 1, 2, 3, 4, 6, 12, 31, 62, 93, 124, 186, 372
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
845 : 1, 5, 13, 65, 169, 845
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 908,372,780,845, is 1.
Now, the common factors can be found like this.
908:2x 2x 227
372:2x 2x 3x 31
780:2x 2x 3x 5x 13
845:5x 13x 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 2x 2x 2x 3x 5x 13 = 3120
Therefore, the value for common factors is 3120.
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 = 222628161600/(1x3120)
LCM = 222628161600/3120
LCM = 71355180
Thus, we can understand that the LCM of 908,372,780,845 is 71355180.
