Given numbers are 400,109,580,673,778
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 400,109,580,673,778 is 331016126800.
Find LCM of 400,109,580,673,778 with Prime Factorization
| 2 | 400, 109, 580, 673, 778 |
| 2 | 200, 109, 290, 673, 389 |
| 5 | 100, 109, 145, 673, 389 |
| 20, 109, 29, 673, 389 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 20 x 109 x 29 x 673 x 389 = 331016126800
Therefore, the lowest common multiple of 400,109,580,673,778 is 331016126800.
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.
400 x 109 x 580 x 673 x 778 = 13240645072000
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.
400 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, 400
109 : 1, 109
580 : 1, 2, 4, 5, 10, 20, 29, 58, 116, 145, 290, 580
673 : 1, 673
778 : 1, 2, 389, 778
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 400,109,580,673,778, is 1.
Now, the common factors can be found like this.
400:2x 2x 2x 2x 5x 5
109:109
580:2x 2x 5x 29
673:673
778:2x 389
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 5 = 40
Therefore, the value for common factors is 40.
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 = 13240645072000/(1x40)
LCM = 13240645072000/40
LCM = 331016126800
Thus, we can understand that the LCM of 400,109,580,673,778 is 331016126800.
