Given numbers are 879,647,459,138
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 879,647,459,138 is 4002602094.
Find LCM of 879,647,459,138 with Prime Factorization
| 3 | 879, 647, 459, 138 |
| 293, 647, 153, 46 |
Multiply the prime numbers at the bottom and the left side.
3 x 293 x 647 x 153 x 46 = 4002602094
Therefore, the lowest common multiple of 879,647,459,138 is 4002602094.
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.
879 x 647 x 459 x 138 = 36023418846
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.
879 : 1, 3, 293, 879
647 : 1, 647
459 : 1, 3, 9, 17, 27, 51, 153, 459
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 879,647,459,138, is 1.
Now, the common factors can be found like this.
879:3x 293
647:647
459:3x 3x 3x 17
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.
3x 3 = 9
Therefore, the value for common factors is 9.
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 = 36023418846/(1x9)
LCM = 36023418846/9
LCM = 4002602094
Thus, we can understand that the LCM of 879,647,459,138 is 4002602094.
