Find LCM of 799,945,540,842 with Prime Factorization
| 2 | 799, 945, 540, 842 |
| 3 | 799, 945, 270, 421 |
| 3 | 799, 315, 90, 421 |
| 3 | 799, 105, 30, 421 |
| 5 | 799, 35, 10, 421 |
| 799, 7, 2, 421 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 5 x 799 x 7 x 2 x 421 = 1271512620
Therefore, the lowest common multiple of 799,945,540,842 is 1271512620.
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 945 x 540 x 842 = 343308407400
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
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
540 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 27, 30, 36, 45, 54, 60, 90, 108, 135, 180, 270, 540
842 : 1, 2, 421, 842
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 799,945,540,842, is 1.
Now, the common factors can be found like this.
799:17x 47
945:3x 3x 3x 5x 7
540:2x 2x 3x 3x 3x 5
842:2x 421
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 3x 3x 5 = 270
Therefore, the value for common factors is 270.
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 = 343308407400/(1x270)
LCM = 343308407400/270
LCM = 1271512620
Thus, we can understand that the LCM of 799,945,540,842 is 1271512620.
