Find LCM of 665,200,819,100,897 with Prime Factorization
| 2 | 665, 200, 819, 100, 897 |
| 2 | 665, 100, 819, 50, 897 |
| 3 | 665, 25, 819, 50, 897 |
| 5 | 665, 25, 273, 50, 299 |
| 5 | 133, 5, 273, 10, 299 |
| 7 | 133, 1, 273, 2, 299 |
| 13 | 19, 1, 39, 2, 299 |
| 19, 1, 3, 2, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 5 x 7 x 13 x 19 x 1 x 3 x 2 x 23 = 71580600
Therefore, the lowest common multiple of 665,200,819,100,897 is 71580600.
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.
665 x 200 x 819 x 100 x 897 = 9770751900000
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.
665 : 1, 5, 7, 19, 35, 95, 133, 665
200 : 1, 2, 4, 5, 8, 10, 20, 25, 40, 50, 100, 200
819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819
100 : 1, 2, 4, 5, 10, 20, 25, 50, 100
897 : 1, 3, 13, 23, 39, 69, 299, 897
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 665,200,819,100,897, is 1.
Now, the common factors can be found like this.
665:5x 7x 19
200:2x 2x 2x 5x 5
819:3x 3x 7x 13
100:2x 2x 5x 5
897:3x 13x 23
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 5x 5x 7x 13 = 136500
Therefore, the value for common factors is 136500.
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 = 9770751900000/(1x136500)
LCM = 9770751900000/136500
LCM = 71580600
Thus, we can understand that the LCM of 665,200,819,100,897 is 71580600.
