Given numbers are 398,586,713,391,138
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 398,586,713,391,138 is 4240434882.
Find LCM of 398,586,713,391,138 with Prime Factorization
| 2 | 398, 586, 713, 391, 138 |
| 23 | 199, 293, 713, 391, 69 |
| 199, 293, 31, 17, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 23 x 199 x 293 x 31 x 17 x 3 = 4240434882
Therefore, the lowest common multiple of 398,586,713,391,138 is 4240434882.
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.
398 x 586 x 713 x 391 x 138 = 8972760210312
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.
398 : 1, 2, 199, 398
586 : 1, 2, 293, 586
713 : 1, 23, 31, 713
391 : 1, 17, 23, 391
138 : 1, 2, 3, 6, 23, 46, 69, 138
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 398,586,713,391,138, is 1.
Now, the common factors can be found like this.
398:2x 199
586:2x 293
713:23x 31
391:17x 23
138:2x 3x 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 23x 23 = 2116
Therefore, the value for common factors is 2116.
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 = 8972760210312/(1x2116)
LCM = 8972760210312/2116
LCM = 4240434882
Thus, we can understand that the LCM of 398,586,713,391,138 is 4240434882.
