Given numbers are 725,741,640,324
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 725,741,640,324 is 1856649600.
Find LCM of 725,741,640,324 with Prime Factorization
| 2 | 725, 741, 640, 324 |
| 2 | 725, 741, 320, 162 |
| 3 | 725, 741, 160, 81 |
| 5 | 725, 247, 160, 27 |
| 145, 247, 32, 27 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 145 x 247 x 32 x 27 = 1856649600
Therefore, the lowest common multiple of 725,741,640,324 is 1856649600.
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 741 x 640 x 324 = 111398976000
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
741 : 1, 3, 13, 19, 39, 57, 247, 741
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
324 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 324
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 725,741,640,324, is 1.
Now, the common factors can be found like this.
725:5x 5x 29
741:3x 13x 19
640:2x 2x 2x 2x 2x 2x 2x 5
324:2x 2x 3x 3x 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 3x 5 = 60
Therefore, the value for common factors is 60.
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 = 111398976000/(1x60)
LCM = 111398976000/60
LCM = 1856649600
Thus, we can understand that the LCM of 725,741,640,324 is 1856649600.
