Given numbers are 578,172,606,303,391
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 578,172,606,303,391 is 346415052.
Find LCM of 578,172,606,303,391 with Prime Factorization
| 2 | 578, 172, 606, 303, 391 |
| 3 | 289, 86, 303, 303, 391 |
| 17 | 289, 86, 101, 101, 391 |
| 101 | 17, 86, 101, 101, 23 |
| 17, 86, 1, 1, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 17 x 101 x 17 x 86 x 1 x 1 x 23 = 346415052
Therefore, the lowest common multiple of 578,172,606,303,391 is 346415052.
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.
578 x 172 x 606 x 303 x 391 = 7137535731408
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.
578 : 1, 2, 17, 34, 289, 578
172 : 1, 2, 4, 43, 86, 172
606 : 1, 2, 3, 6, 101, 202, 303, 606
303 : 1, 3, 101, 303
391 : 1, 17, 23, 391
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 578,172,606,303,391, is 1.
Now, the common factors can be found like this.
578:2x 17x 17
172:2x 2x 43
606:2x 3x 101
303:3x 101
391:17x 23
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 17x 101 = 20604
Therefore, the value for common factors is 20604.
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 = 7137535731408/(1x20604)
LCM = 7137535731408/20604
LCM = 346415052
Thus, we can understand that the LCM of 578,172,606,303,391 is 346415052.
