Given numbers are 289,578,406,470
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 289,578,406,470 is 27573490.
Find LCM of 289,578,406,470 with Prime Factorization
| 2 | 289, 578, 406, 470 |
| 17 | 289, 289, 203, 235 |
| 17 | 17, 17, 203, 235 |
| 1, 1, 203, 235 |
Multiply the prime numbers at the bottom and the left side.
2 x 17 x 17 x 1 x 1 x 203 x 235 = 27573490
Therefore, the lowest common multiple of 289,578,406,470 is 27573490.
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.
289 x 578 x 406 x 470 = 31874954440
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.
289 : 1, 17, 289
578 : 1, 2, 17, 34, 289, 578
406 : 1, 2, 7, 14, 29, 58, 203, 406
470 : 1, 2, 5, 10, 47, 94, 235, 470
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 289,578,406,470, is 1.
Now, the common factors can be found like this.
289:17x 17
578:2x 17x 17
406:2x 7x 29
470:2x 5x 47
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 17x 17 = 1156
Therefore, the value for common factors is 1156.
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 = 31874954440/(1x1156)
LCM = 31874954440/1156
LCM = 27573490
Thus, we can understand that the LCM of 289,578,406,470 is 27573490.
