Given numbers are 157,837,605,825
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 157,837,605,825 is 397512225.
Find LCM of 157,837,605,825 with Prime Factorization
| 3 | 157, 837, 605, 825 |
| 5 | 157, 279, 605, 275 |
| 11 | 157, 279, 121, 55 |
| 157, 279, 11, 5 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 11 x 157 x 279 x 11 x 5 = 397512225
Therefore, the lowest common multiple of 157,837,605,825 is 397512225.
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.
157 x 837 x 605 x 825 = 65589517125
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.
157 : 1, 157
837 : 1, 3, 9, 27, 31, 93, 279, 837
605 : 1, 5, 11, 55, 121, 605
825 : 1, 3, 5, 11, 15, 25, 33, 55, 75, 165, 275, 825
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 157,837,605,825, is 1.
Now, the common factors can be found like this.
157:157
837:3x 3x 3x 31
605:5x 11x 11
825:3x 5x 5x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 11 = 165
Therefore, the value for common factors is 165.
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 = 65589517125/(1x165)
LCM = 65589517125/165
LCM = 397512225
Thus, we can understand that the LCM of 157,837,605,825 is 397512225.
