The LCM of 479,618,721,798 is 39370926.
Find LCM of 479,618,721,798 with Prime Factorization
| 2 | 479, 618, 721, 798 |
| 3 | 479, 309, 721, 399 |
| 7 | 479, 103, 721, 133 |
| 103 | 479, 103, 103, 19 |
| 479, 1, 1, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 103 x 479 x 1 x 1 x 19 = 39370926
Therefore, the lowest common multiple of 479,618,721,798 is 39370926.
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.
479 x 618 x 721 x 798 = 170318625876
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.
479 : 1, 479
618 : 1, 2, 3, 6, 103, 206, 309, 618
721 : 1, 7, 103, 721
798 : 1, 2, 3, 6, 7, 14, 19, 21, 38, 42, 57, 114, 133, 266, 399, 798
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 479,618,721,798, is 1.
Now, the common factors can be found like this.
479:479
618:2x 3x 103
721:7x 103
798:2x 3x 7x 19
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 7x 103 = 4326
Therefore, the value for common factors is 4326.
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 = 170318625876/(1x4326)
LCM = 170318625876/4326
LCM = 39370926
Thus, we can understand that the LCM of 479,618,721,798 is 39370926.
