The LCM of 794,348,638,957 is 1519716.
Find LCM of 794,348,638,957 with Prime Factorization
2 | 794, 348, 638, 957 |
3 | 397, 174, 319, 957 |
11 | 397, 58, 319, 319 |
29 | 397, 58, 29, 29 |
397, 2, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 29 x 397 x 2 x 1 x 1 = 1519716
Therefore, the lowest common multiple of 794,348,638,957 is 1519716.
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.
794 x 348 x 638 x 957 = 168706712592
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.
794 : 1, 2, 397, 794
348 : 1, 2, 3, 4, 6, 12, 29, 58, 87, 116, 174, 348
638 : 1, 2, 11, 22, 29, 58, 319, 638
957 : 1, 3, 11, 29, 33, 87, 319, 957
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 794,348,638,957, is 1.
Now, the common factors can be found like this.
794:2x 397
348:2x 2x 3x 29
638:2x 11x 29
957:3x 11x 29
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 3x 11x 29x 29 = 111012
Therefore, the value for common factors is 111012.
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 = 168706712592/(1x111012)
LCM = 168706712592/111012
LCM = 1519716
Thus, we can understand that the LCM of 794,348,638,957 is 1519716.
