Find LCM of 829,720,136,918 with Prime Factorization
| 2 | 829, 720, 136, 918 |
| 2 | 829, 360, 68, 459 |
| 2 | 829, 180, 34, 459 |
| 3 | 829, 90, 17, 459 |
| 3 | 829, 30, 17, 153 |
| 17 | 829, 10, 17, 51 |
| 829, 10, 1, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 3 x 17 x 829 x 10 x 1 x 3 = 30440880
Therefore, the lowest common multiple of 829,720,136,918 is 30440880.
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 720 x 136 x 918 = 74519274240
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
720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720
136 : 1, 2, 4, 8, 17, 34, 68, 136
918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 829,720,136,918, is 1.
Now, the common factors can be found like this.
829:829
720:2x 2x 2x 2x 3x 3x 5
136:2x 2x 2x 17
918:2x 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 2x 2x 2x 3x 3x 17 = 2448
Therefore, the value for common factors is 2448.
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 = 74519274240/(1x2448)
LCM = 74519274240/2448
LCM = 30440880
Thus, we can understand that the LCM of 829,720,136,918 is 30440880.
