Given numbers are 349,381,658,470,290
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 349,381,658,470,290 is 12686572290.
Find LCM of 349,381,658,470,290 with Prime Factorization
| 2 | 349, 381, 658, 470, 290 |
| 5 | 349, 381, 329, 235, 145 |
| 47 | 349, 381, 329, 47, 29 |
| 349, 381, 7, 1, 29 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 47 x 349 x 381 x 7 x 1 x 29 = 12686572290
Therefore, the lowest common multiple of 349,381,658,470,290 is 12686572290.
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.
349 x 381 x 658 x 470 x 290 = 11925377952600
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.
349 : 1, 349
381 : 1, 3, 127, 381
658 : 1, 2, 7, 14, 47, 94, 329, 658
470 : 1, 2, 5, 10, 47, 94, 235, 470
290 : 1, 2, 5, 10, 29, 58, 145, 290
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 349,381,658,470,290, is 1.
Now, the common factors can be found like this.
349:349
381:3x 127
658:2x 7x 47
470:2x 5x 47
290:2x 5x 29
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 5x 47 = 940
Therefore, the value for common factors is 940.
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 = 11925377952600/(1x940)
LCM = 11925377952600/940
LCM = 12686572290
Thus, we can understand that the LCM of 349,381,658,470,290 is 12686572290.
