Given numbers are 879,646,638,125
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 879,646,638,125 is 22642380750.
Find LCM of 879,646,638,125 with Prime Factorization
| 2 | 879, 646, 638, 125 |
| 879, 323, 319, 125 |
Multiply the prime numbers at the bottom and the left side.
2 x 879 x 323 x 319 x 125 = 22642380750
Therefore, the lowest common multiple of 879,646,638,125 is 22642380750.
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 646 x 638 x 125 = 45284761500
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
646 : 1, 2, 17, 19, 34, 38, 323, 646
638 : 1, 2, 11, 22, 29, 58, 319, 638
125 : 1, 5, 25, 125
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 879,646,638,125, is 1.
Now, the common factors can be found like this.
879:3x 293
646:2x 17x 19
638:2x 11x 29
125:5x 5x 5
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 45284761500/(1x2)
LCM = 45284761500/2
LCM = 22642380750
Thus, we can understand that the LCM of 879,646,638,125 is 22642380750.
