The LCM of 517,978,105,910 is 230059830.
Find LCM of 517,978,105,910 with Prime Factorization
| 2 | 517, 978, 105, 910 |
| 3 | 517, 489, 105, 455 |
| 5 | 517, 163, 35, 455 |
| 7 | 517, 163, 7, 91 |
| 517, 163, 1, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 7 x 517 x 163 x 1 x 13 = 230059830
Therefore, the lowest common multiple of 517,978,105,910 is 230059830.
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 978 x 105 x 910 = 48312564300
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
978 : 1, 2, 3, 6, 163, 326, 489, 978
105 : 1, 3, 5, 7, 15, 21, 35, 105
910 : 1, 2, 5, 7, 10, 13, 14, 26, 35, 65, 70, 91, 130, 182, 455, 910
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 517,978,105,910, is 1.
Now, the common factors can be found like this.
517:11x 47
978:2x 3x 163
105:3x 5x 7
910:2x 5x 7x 13
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 5x 7 = 210
Therefore, the value for common factors is 210.
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 = 48312564300/(1x210)
LCM = 48312564300/210
LCM = 230059830
Thus, we can understand that the LCM of 517,978,105,910 is 230059830.
