Find LCM of 909,858,794,623,847 with Prime Factorization
| 2 | 909, 858, 794, 623, 847 |
| 3 | 909, 429, 397, 623, 847 |
| 7 | 303, 143, 397, 623, 847 |
| 11 | 303, 143, 397, 89, 121 |
| 303, 13, 397, 89, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 11 x 303 x 13 x 397 x 89 x 11 = 707295923334
Therefore, the lowest common multiple of 909,858,794,623,847 is 707295923334.
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.
909 x 858 x 794 x 623 x 847 = 326770716580308
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.
909 : 1, 3, 9, 101, 303, 909
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
794 : 1, 2, 397, 794
623 : 1, 7, 89, 623
847 : 1, 7, 11, 77, 121, 847
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 909,858,794,623,847, is 1.
Now, the common factors can be found like this.
909:3x 3x 101
858:2x 3x 11x 13
794:2x 397
623:7x 89
847:7x 11x 11
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 11 = 462
Therefore, the value for common factors is 462.
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 = 326770716580308/(1x462)
LCM = 326770716580308/462
LCM = 707295923334
Thus, we can understand that the LCM of 909,858,794,623,847 is 707295923334.
