Given numbers are 658,138,310,827,423
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 658,138,310,827,423 is 17459566110.
Find LCM of 658,138,310,827,423 with Prime Factorization
| 2 | 658, 138, 310, 827, 423 |
| 3 | 329, 69, 155, 827, 423 |
| 47 | 329, 23, 155, 827, 141 |
| 7, 23, 155, 827, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 47 x 7 x 23 x 155 x 827 x 3 = 17459566110
Therefore, the lowest common multiple of 658,138,310,827,423 is 17459566110.
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.
658 x 138 x 310 x 827 x 423 = 9847195286040
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.
658 : 1, 2, 7, 14, 47, 94, 329, 658
138 : 1, 2, 3, 6, 23, 46, 69, 138
310 : 1, 2, 5, 10, 31, 62, 155, 310
827 : 1, 827
423 : 1, 3, 9, 47, 141, 423
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 658,138,310,827,423, is 1.
Now, the common factors can be found like this.
658:2x 7x 47
138:2x 3x 23
310:2x 5x 31
827:827
423:3x 3x 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 3x 47 = 564
Therefore, the value for common factors is 564.
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 = 9847195286040/(1x564)
LCM = 9847195286040/564
LCM = 17459566110
Thus, we can understand that the LCM of 658,138,310,827,423 is 17459566110.
