Find LCM of 917,187,489,782,693 with Prime Factorization
| 3 | 917, 187, 489, 782, 693 |
| 7 | 917, 187, 163, 782, 231 |
| 11 | 131, 187, 163, 782, 33 |
| 17 | 131, 17, 163, 782, 3 |
| 131, 1, 163, 46, 3 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 11 x 17 x 131 x 1 x 163 x 46 x 3 = 11571745878
Therefore, the lowest common multiple of 917,187,489,782,693 is 11571745878.
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.
917 x 187 x 489 x 782 x 693 = 45442246062906
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.
917 : 1, 7, 131, 917
187 : 1, 11, 17, 187
489 : 1, 3, 163, 489
782 : 1, 2, 17, 23, 34, 46, 391, 782
693 : 1, 3, 7, 9, 11, 21, 33, 63, 77, 99, 231, 693
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 917,187,489,782,693, is 1.
Now, the common factors can be found like this.
917:7x 131
187:11x 17
489:3x 163
782:2x 17x 23
693:3x 3x 7x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 7x 11x 17 = 3927
Therefore, the value for common factors is 3927.
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 = 45442246062906/(1x3927)
LCM = 45442246062906/3927
LCM = 11571745878
Thus, we can understand that the LCM of 917,187,489,782,693 is 11571745878.
