Find LCM of 765,663,287,466,639 with Prime Factorization
| 3 | 765, 663, 287, 466, 639 |
| 3 | 255, 221, 287, 466, 213 |
| 17 | 85, 221, 287, 466, 71 |
| 5, 13, 287, 466, 71 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 17 x 5 x 13 x 287 x 466 x 71 = 94434557490
Therefore, the lowest common multiple of 765,663,287,466,639 is 94434557490.
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.
765 x 663 x 287 x 466 x 639 = 43345461887910
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.
765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765
663 : 1, 3, 13, 17, 39, 51, 221, 663
287 : 1, 7, 41, 287
466 : 1, 2, 233, 466
639 : 1, 3, 9, 71, 213, 639
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 765,663,287,466,639, is 1.
Now, the common factors can be found like this.
765:3x 3x 5x 17
663:3x 13x 17
287:7x 41
466:2x 233
639:3x 3x 71
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 17 = 459
Therefore, the value for common factors is 459.
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 = 43345461887910/(1x459)
LCM = 43345461887910/459
LCM = 94434557490
Thus, we can understand that the LCM of 765,663,287,466,639 is 94434557490.
