Given numbers are 908,552,638,423
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 908,552,638,423 is 5636048616.
Find LCM of 908,552,638,423 with Prime Factorization
| 2 | 908, 552, 638, 423 |
| 2 | 454, 276, 319, 423 |
| 3 | 227, 138, 319, 423 |
| 227, 46, 319, 141 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 227 x 46 x 319 x 141 = 5636048616
Therefore, the lowest common multiple of 908,552,638,423 is 5636048616.
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.
908 x 552 x 638 x 423 = 135265166784
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.
908 : 1, 2, 4, 227, 454, 908
552 : 1, 2, 3, 4, 6, 8, 12, 23, 24, 46, 69, 92, 138, 184, 276, 552
638 : 1, 2, 11, 22, 29, 58, 319, 638
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 908,552,638,423, is 1.
Now, the common factors can be found like this.
908:2x 2x 227
552:2x 2x 2x 3x 23
638:2x 11x 29
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 2x 3 = 24
Therefore, the value for common factors is 24.
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 = 135265166784/(1x24)
LCM = 135265166784/24
LCM = 5636048616
Thus, we can understand that the LCM of 908,552,638,423 is 5636048616.
