Given numbers are 860,643,103,634
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 860,643,103,634 is 18055349980.
Find LCM of 860,643,103,634 with Prime Factorization
| 2 | 860, 643, 103, 634 |
| 430, 643, 103, 317 |
Multiply the prime numbers at the bottom and the left side.
2 x 430 x 643 x 103 x 317 = 18055349980
Therefore, the lowest common multiple of 860,643,103,634 is 18055349980.
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.
860 x 643 x 103 x 634 = 36110699960
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.
860 : 1, 2, 4, 5, 10, 20, 43, 86, 172, 215, 430, 860
643 : 1, 643
103 : 1, 103
634 : 1, 2, 317, 634
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 860,643,103,634, is 1.
Now, the common factors can be found like this.
860:2x 2x 5x 43
643:643
103:103
634:2x 317
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 = 36110699960/(1x2)
LCM = 36110699960/2
LCM = 18055349980
Thus, we can understand that the LCM of 860,643,103,634 is 18055349980.
