Find LCM of 205,487,105,945,910 with Prime Factorization
3 | 205, 487, 105, 945, 910 |
5 | 205, 487, 35, 315, 910 |
7 | 41, 487, 7, 63, 182 |
41, 487, 1, 9, 26 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 7 x 41 x 487 x 1 x 9 x 26 = 490589190
Therefore, the lowest common multiple of 205,487,105,945,910 is 490589190.
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.
205 x 487 x 105 x 945 x 910 = 9014576366250
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.
205 : 1, 5, 41, 205
487 : 1, 487
105 : 1, 3, 5, 7, 15, 21, 35, 105
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
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 205,487,105,945,910, is 1.
Now, the common factors can be found like this.
205:5x 41
487:487
105:3x 5x 7
945:3x 3x 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.
3x 5x 5x 5x 7x 7 = 18375
Therefore, the value for common factors is 18375.
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 = 9014576366250/(1x18375)
LCM = 9014576366250/18375
LCM = 490589190
Thus, we can understand that the LCM of 205,487,105,945,910 is 490589190.
