Find LCM of 829,717,756,980,447 with Prime Factorization
| 2 | 829, 717, 756, 980, 447 |
| 2 | 829, 717, 378, 490, 447 |
| 3 | 829, 717, 189, 245, 447 |
| 7 | 829, 239, 63, 245, 149 |
| 829, 239, 9, 35, 149 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 829 x 239 x 9 x 35 x 149 = 781139392740
Therefore, the lowest common multiple of 829,717,756,980,447 is 781139392740.
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 717 x 756 x 980 x 447 = 196847126970480
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
717 : 1, 3, 239, 717
756 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 27, 28, 36, 42, 54, 63, 84, 108, 126, 189, 252, 378, 756
980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980
447 : 1, 3, 149, 447
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 829,717,756,980,447, is 1.
Now, the common factors can be found like this.
829:829
717:3x 239
756:2x 2x 3x 3x 3x 7
980:2x 2x 5x 7x 7
447:3x 149
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 3x 7 = 252
Therefore, the value for common factors is 252.
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 = 196847126970480/(1x252)
LCM = 196847126970480/252
LCM = 781139392740
Thus, we can understand that the LCM of 829,717,756,980,447 is 781139392740.
