The LCM of 517,721,912,168,410 is 69690648720.
Find LCM of 517,721,912,168,410 with Prime Factorization
| 2 | 517, 721, 912, 168, 410 |
| 2 | 517, 721, 456, 84, 205 |
| 2 | 517, 721, 228, 42, 205 |
| 3 | 517, 721, 114, 21, 205 |
| 7 | 517, 721, 38, 7, 205 |
| 517, 103, 38, 1, 205 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 7 x 517 x 103 x 38 x 1 x 205 = 69690648720
Therefore, the lowest common multiple of 517,721,912,168,410 is 69690648720.
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.
517 x 721 x 912 x 168 x 410 = 23416057969920
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.
517 : 1, 11, 47, 517
721 : 1, 7, 103, 721
912 : 1, 2, 3, 4, 6, 8, 12, 16, 19, 24, 38, 48, 57, 76, 114, 152, 228, 304, 456, 912
168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168
410 : 1, 2, 5, 10, 41, 82, 205, 410
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 517,721,912,168,410, is 1.
Now, the common factors can be found like this.
517:11x 47
721:7x 103
912:2x 2x 2x 2x 3x 19
168:2x 2x 2x 3x 7
410:2x 5x 41
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 7 = 336
Therefore, the value for common factors is 336.
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 = 23416057969920/(1x336)
LCM = 23416057969920/336
LCM = 69690648720
Thus, we can understand that the LCM of 517,721,912,168,410 is 69690648720.
