Find LCM of 663,675,391,117,197 with Prime Factorization
| 3 | 663, 675, 391, 117, 197 |
| 3 | 221, 225, 391, 39, 197 |
| 13 | 221, 75, 391, 13, 197 |
| 17 | 17, 75, 391, 1, 197 |
| 1, 75, 23, 1, 197 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 13 x 17 x 1 x 75 x 23 x 1 x 197 = 675911925
Therefore, the lowest common multiple of 663,675,391,117,197 is 675911925.
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.
663 x 675 x 391 x 117 x 197 = 4033166456475
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.
663 : 1, 3, 13, 17, 39, 51, 221, 663
675 : 1, 3, 5, 9, 15, 25, 27, 45, 75, 135, 225, 675
391 : 1, 17, 23, 391
117 : 1, 3, 9, 13, 39, 117
197 : 1, 197
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 663,675,391,117,197, is 1.
Now, the common factors can be found like this.
663:3x 13x 17
675:3x 3x 3x 5x 5
391:17x 23
117:3x 3x 13
197:197
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 13x 17 = 5967
Therefore, the value for common factors is 5967.
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 = 4033166456475/(1x5967)
LCM = 4033166456475/5967
LCM = 675911925
Thus, we can understand that the LCM of 663,675,391,117,197 is 675911925.
