Given numbers are 879,958,391,642
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 879,958,391,642 is 35230184634.
Find LCM of 879,958,391,642 with Prime Factorization
| 2 | 879, 958, 391, 642 |
| 3 | 879, 479, 391, 321 |
| 293, 479, 391, 107 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 293 x 479 x 391 x 107 = 35230184634
Therefore, the lowest common multiple of 879,958,391,642 is 35230184634.
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 958 x 391 x 642 = 211381107804
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
958 : 1, 2, 479, 958
391 : 1, 17, 23, 391
642 : 1, 2, 3, 6, 107, 214, 321, 642
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 879,958,391,642, is 1.
Now, the common factors can be found like this.
879:3x 293
958:2x 479
391:17x 23
642:2x 3x 107
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3 = 6
Therefore, the value for common factors is 6.
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 = 211381107804/(1x6)
LCM = 211381107804/6
LCM = 35230184634
Thus, we can understand that the LCM of 879,958,391,642 is 35230184634.
