Given numbers are 860,370,667,400,807
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 860,370,667,400,807 is 342554391600.
Find LCM of 860,370,667,400,807 with Prime Factorization
| 2 | 860, 370, 667, 400, 807 |
| 2 | 430, 185, 667, 200, 807 |
| 5 | 215, 185, 667, 100, 807 |
| 43, 37, 667, 20, 807 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 43 x 37 x 667 x 20 x 807 = 342554391600
Therefore, the lowest common multiple of 860,370,667,400,807 is 342554391600.
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 370 x 667 x 400 x 807 = 68510878320000
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
370 : 1, 2, 5, 10, 37, 74, 185, 370
667 : 1, 23, 29, 667
400 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, 400
807 : 1, 3, 269, 807
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 860,370,667,400,807, is 1.
Now, the common factors can be found like this.
860:2x 2x 5x 43
370:2x 5x 37
667:23x 29
400:2x 2x 2x 2x 5x 5
807:3x 269
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 5x 5 = 200
Therefore, the value for common factors is 200.
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 = 68510878320000/(1x200)
LCM = 68510878320000/200
LCM = 342554391600
Thus, we can understand that the LCM of 860,370,667,400,807 is 342554391600.
