Find LCM of 714,515,760,489,686 with Prime Factorization
| 2 | 714, 515, 760, 489, 686 |
| 3 | 357, 515, 380, 489, 343 |
| 5 | 119, 515, 380, 163, 343 |
| 7 | 119, 103, 76, 163, 343 |
| 17, 103, 76, 163, 49 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 7 x 17 x 103 x 76 x 163 x 49 = 223204382520
Therefore, the lowest common multiple of 714,515,760,489,686 is 223204382520.
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.
714 x 515 x 760 x 489 x 686 = 93745840658400
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.
714 : 1, 2, 3, 6, 7, 14, 17, 21, 34, 42, 51, 102, 119, 238, 357, 714
515 : 1, 5, 103, 515
760 : 1, 2, 4, 5, 8, 10, 19, 20, 38, 40, 76, 95, 152, 190, 380, 760
489 : 1, 3, 163, 489
686 : 1, 2, 7, 14, 49, 98, 343, 686
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 714,515,760,489,686, is 1.
Now, the common factors can be found like this.
714:2x 3x 7x 17
515:5x 103
760:2x 2x 2x 5x 19
489:3x 163
686:2x 7x 7x 7
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 5x 7 = 420
Therefore, the value for common factors is 420.
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 = 93745840658400/(1x420)
LCM = 93745840658400/420
LCM = 223204382520
Thus, we can understand that the LCM of 714,515,760,489,686 is 223204382520.
