Find LCM of 725,928,155,144 with Prime Factorization
| 2 | 725, 928, 155, 144 |
| 2 | 725, 464, 155, 72 |
| 2 | 725, 232, 155, 36 |
| 2 | 725, 116, 155, 18 |
| 5 | 725, 58, 155, 9 |
| 29 | 145, 58, 31, 9 |
| 5, 2, 31, 9 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 5 x 29 x 5 x 2 x 31 x 9 = 6472800
Therefore, the lowest common multiple of 725,928,155,144 is 6472800.
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.
725 x 928 x 155 x 144 = 15016896000
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.
725 : 1, 5, 25, 29, 145, 725
928 : 1, 2, 4, 8, 16, 29, 32, 58, 116, 232, 464, 928
155 : 1, 5, 31, 155
144 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 36, 48, 72, 144
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 725,928,155,144, is 1.
Now, the common factors can be found like this.
725:5x 5x 29
928:2x 2x 2x 2x 2x 29
155:5x 31
144:2x 2x 2x 2x 3x 3
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 5x 29 = 2320
Therefore, the value for common factors is 2320.
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 = 15016896000/(1x2320)
LCM = 15016896000/2320
LCM = 6472800
Thus, we can understand that the LCM of 725,928,155,144 is 6472800.
