The LCM of 829,693,913,990 is 476832510.
Find LCM of 829,693,913,990 with Prime Factorization
| 3 | 829, 693, 913, 990 |
| 3 | 829, 231, 913, 330 |
| 11 | 829, 77, 913, 110 |
| 829, 7, 83, 10 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 11 x 829 x 7 x 83 x 10 = 476832510
Therefore, the lowest common multiple of 829,693,913,990 is 476832510.
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.
829 x 693 x 913 x 990 = 519270603390
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.
829 : 1, 829
693 : 1, 3, 7, 9, 11, 21, 33, 63, 77, 99, 231, 693
913 : 1, 11, 83, 913
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 829,693,913,990, is 1.
Now, the common factors can be found like this.
829:829
693:3x 3x 7x 11
913:11x 83
990:2x 3x 3x 5x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 11x 11 = 1089
Therefore, the value for common factors is 1089.
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 = 519270603390/(1x1089)
LCM = 519270603390/1089
LCM = 476832510
Thus, we can understand that the LCM of 829,693,913,990 is 476832510.
