Given numbers are 860,705,428,260,959
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 860,705,428,260,959 is 161757080940.
Find LCM of 860,705,428,260,959 with Prime Factorization
| 2 | 860, 705, 428, 260, 959 |
| 2 | 430, 705, 214, 130, 959 |
| 5 | 215, 705, 107, 65, 959 |
| 43, 141, 107, 13, 959 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 43 x 141 x 107 x 13 x 959 = 161757080940
Therefore, the lowest common multiple of 860,705,428,260,959 is 161757080940.
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 705 x 428 x 260 x 959 = 64702832376000
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
705 : 1, 3, 5, 15, 47, 141, 235, 705
428 : 1, 2, 4, 107, 214, 428
260 : 1, 2, 4, 5, 10, 13, 20, 26, 52, 65, 130, 260
959 : 1, 7, 137, 959
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 860,705,428,260,959, is 1.
Now, the common factors can be found like this.
860:2x 2x 5x 43
705:3x 5x 47
428:2x 2x 107
260:2x 2x 5x 13
959:7x 137
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 2x 5x 5 = 400
Therefore, the value for common factors is 400.
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 = 64702832376000/(1x400)
LCM = 64702832376000/400
LCM = 161757080940
Thus, we can understand that the LCM of 860,705,428,260,959 is 161757080940.
