Find LCM of 863,705,513,551,665 with Prime Factorization
| 3 | 863, 705, 513, 551, 665 |
| 5 | 863, 235, 171, 551, 665 |
| 19 | 863, 47, 171, 551, 133 |
| 863, 47, 9, 29, 7 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 19 x 863 x 47 x 9 x 29 x 7 = 21119909895
Therefore, the lowest common multiple of 863,705,513,551,665 is 21119909895.
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.
863 x 705 x 513 x 551 x 665 = 114364312081425
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.
863 : 1, 863
705 : 1, 3, 5, 15, 47, 141, 235, 705
513 : 1, 3, 9, 19, 27, 57, 171, 513
551 : 1, 19, 29, 551
665 : 1, 5, 7, 19, 35, 95, 133, 665
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 863,705,513,551,665, is 1.
Now, the common factors can be found like this.
863:863
705:3x 5x 47
513:3x 3x 3x 19
551:19x 29
665:5x 7x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 19x 19 = 5415
Therefore, the value for common factors is 5415.
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 = 114364312081425/(1x5415)
LCM = 114364312081425/5415
LCM = 21119909895
Thus, we can understand that the LCM of 863,705,513,551,665 is 21119909895.
