Given numbers are 523,102,204,390,257
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 523,102,204,390,257 is 1782289860.
Find LCM of 523,102,204,390,257 with Prime Factorization
| 2 | 523, 102, 204, 390, 257 |
| 3 | 523, 51, 102, 195, 257 |
| 17 | 523, 17, 34, 65, 257 |
| 523, 1, 2, 65, 257 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 17 x 523 x 1 x 2 x 65 x 257 = 1782289860
Therefore, the lowest common multiple of 523,102,204,390,257 is 1782289860.
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.
523 x 102 x 204 x 390 x 257 = 1090761394320
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.
523 : 1, 523
102 : 1, 2, 3, 6, 17, 34, 51, 102
204 : 1, 2, 3, 4, 6, 12, 17, 34, 51, 68, 102, 204
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
257 : 1, 257
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 523,102,204,390,257, is 1.
Now, the common factors can be found like this.
523:523
102:2x 3x 17
204:2x 2x 3x 17
390:2x 3x 5x 13
257:257
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 3x 17 = 612
Therefore, the value for common factors is 612.
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 = 1090761394320/(1x612)
LCM = 1090761394320/612
LCM = 1782289860
Thus, we can understand that the LCM of 523,102,204,390,257 is 1782289860.
