Given numbers are 725,232,638,855
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 725,232,638,855 is 10909800.
Find LCM of 725,232,638,855 with Prime Factorization
| 2 | 725, 232, 638, 855 |
| 5 | 725, 116, 319, 855 |
| 29 | 145, 116, 319, 171 |
| 5, 4, 11, 171 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 29 x 5 x 4 x 11 x 171 = 10909800
Therefore, the lowest common multiple of 725,232,638,855 is 10909800.
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 232 x 638 x 855 = 91751418000
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
232 : 1, 2, 4, 8, 29, 58, 116, 232
638 : 1, 2, 11, 22, 29, 58, 319, 638
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 725,232,638,855, is 1.
Now, the common factors can be found like this.
725:5x 5x 29
232:2x 2x 2x 29
638:2x 11x 29
855:3x 3x 5x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 29x 29 = 8410
Therefore, the value for common factors is 8410.
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 = 91751418000/(1x8410)
LCM = 91751418000/8410
LCM = 10909800
Thus, we can understand that the LCM of 725,232,638,855 is 10909800.
