Given numbers are 460,138,798,125
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 460,138,798,125 is 4588500.
Find LCM of 460,138,798,125 with Prime Factorization
| 2 | 460, 138, 798, 125 |
| 3 | 230, 69, 399, 125 |
| 5 | 230, 23, 133, 125 |
| 23 | 46, 23, 133, 25 |
| 2, 1, 133, 25 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 23 x 2 x 1 x 133 x 25 = 4588500
Therefore, the lowest common multiple of 460,138,798,125 is 4588500.
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.
460 x 138 x 798 x 125 = 6332130000
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.
460 : 1, 2, 4, 5, 10, 20, 23, 46, 92, 115, 230, 460
138 : 1, 2, 3, 6, 23, 46, 69, 138
798 : 1, 2, 3, 6, 7, 14, 19, 21, 38, 42, 57, 114, 133, 266, 399, 798
125 : 1, 5, 25, 125
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 460,138,798,125, is 1.
Now, the common factors can be found like this.
460:2x 2x 5x 23
138:2x 3x 23
798:2x 3x 7x 19
125:5x 5x 5
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 5x 23 = 1380
Therefore, the value for common factors is 1380.
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 = 6332130000/(1x1380)
LCM = 6332130000/1380
LCM = 4588500
Thus, we can understand that the LCM of 460,138,798,125 is 4588500.
