Find LCM of 861,218,808,287,615 with Prime Factorization
| 2 | 861, 218, 808, 287, 615 |
| 3 | 861, 109, 404, 287, 615 |
| 7 | 287, 109, 404, 287, 205 |
| 41 | 41, 109, 404, 41, 205 |
| 1, 109, 404, 1, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 41 x 1 x 109 x 404 x 1 x 5 = 379149960
Therefore, the lowest common multiple of 861,218,808,287,615 is 379149960.
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.
861 x 218 x 808 x 287 x 615 = 26768745475920
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.
861 : 1, 3, 7, 21, 41, 123, 287, 861
218 : 1, 2, 109, 218
808 : 1, 2, 4, 8, 101, 202, 404, 808
287 : 1, 7, 41, 287
615 : 1, 3, 5, 15, 41, 123, 205, 615
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 861,218,808,287,615, is 1.
Now, the common factors can be found like this.
861:3x 7x 41
218:2x 109
808:2x 2x 2x 101
287:7x 41
615:3x 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 3x 7x 41x 41 = 70602
Therefore, the value for common factors is 70602.
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 = 26768745475920/(1x70602)
LCM = 26768745475920/70602
LCM = 379149960
Thus, we can understand that the LCM of 861,218,808,287,615 is 379149960.
