Given numbers are 858,257,507,195
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 858,257,507,195 is 14332890.
Find LCM of 858,257,507,195 with Prime Factorization
| 3 | 858, 257, 507, 195 |
| 13 | 286, 257, 169, 65 |
| 22, 257, 13, 5 |
Multiply the prime numbers at the bottom and the left side.
3 x 13 x 22 x 257 x 13 x 5 = 14332890
Therefore, the lowest common multiple of 858,257,507,195 is 14332890.
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.
858 x 257 x 507 x 195 = 21800325690
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.
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
257 : 1, 257
507 : 1, 3, 13, 39, 169, 507
195 : 1, 3, 5, 13, 15, 39, 65, 195
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 858,257,507,195, is 1.
Now, the common factors can be found like this.
858:2x 3x 11x 13
257:257
507:3x 13x 13
195:3x 5x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 13x 13 = 1521
Therefore, the value for common factors is 1521.
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 = 21800325690/(1x1521)
LCM = 21800325690/1521
LCM = 14332890
Thus, we can understand that the LCM of 858,257,507,195 is 14332890.
