Given numbers are 408,780,725,968
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 408,780,725,968 is 465293400.
Find LCM of 408,780,725,968 with Prime Factorization
| 2 | 408, 780, 725, 968 |
| 2 | 204, 390, 725, 484 |
| 2 | 102, 195, 725, 242 |
| 3 | 51, 195, 725, 121 |
| 5 | 17, 65, 725, 121 |
| 17, 13, 145, 121 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 17 x 13 x 145 x 121 = 465293400
Therefore, the lowest common multiple of 408,780,725,968 is 465293400.
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.
408 x 780 x 725 x 968 = 223340832000
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.
408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408
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
725 : 1, 5, 25, 29, 145, 725
968 : 1, 2, 4, 8, 11, 22, 44, 88, 121, 242, 484, 968
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 408,780,725,968, is 1.
Now, the common factors can be found like this.
408:2x 2x 2x 3x 17
780:2x 2x 3x 5x 13
725:5x 5x 29
968:2x 2x 2x 11x 11
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 2x 3x 5 = 480
Therefore, the value for common factors is 480.
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 = 223340832000/(1x480)
LCM = 223340832000/480
LCM = 465293400
Thus, we can understand that the LCM of 408,780,725,968 is 465293400.
