Given numbers are 799,102,646,459
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 799,102,646,459 is 819774.
Find LCM of 799,102,646,459 with Prime Factorization
| 2 | 799, 102, 646, 459 |
| 3 | 799, 51, 323, 459 |
| 17 | 799, 17, 323, 153 |
| 47, 1, 19, 9 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 17 x 47 x 1 x 19 x 9 = 819774
Therefore, the lowest common multiple of 799,102,646,459 is 819774.
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.
799 x 102 x 646 x 459 = 24165297972
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.
799 : 1, 17, 47, 799
102 : 1, 2, 3, 6, 17, 34, 51, 102
646 : 1, 2, 17, 19, 34, 38, 323, 646
459 : 1, 3, 9, 17, 27, 51, 153, 459
17 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 799,102,646,459, is 17.
Now, the common factors can be found like this.
799:17x 47
102:2x 3x 17
646:2x 17x 19
459:3x 3x 3x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 17x 17 = 1734
Therefore, the value for common factors is 1734.
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 = 24165297972/(17x1734)
LCM = 24165297972/29478
LCM = 819774
Thus, we can understand that the LCM of 799,102,646,459 is 819774.
