Find LCM of 657,576,408,117,418 with Prime Factorization
| 2 | 657, 576, 408, 117, 418 |
| 2 | 657, 288, 204, 117, 209 |
| 2 | 657, 144, 102, 117, 209 |
| 3 | 657, 72, 51, 117, 209 |
| 3 | 219, 24, 17, 39, 209 |
| 73, 8, 17, 13, 209 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 3 x 73 x 8 x 17 x 13 x 209 = 1942155072
Therefore, the lowest common multiple of 657,576,408,117,418 is 1942155072.
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.
657 x 576 x 408 x 117 x 418 = 7551098919936
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.
657 : 1, 3, 9, 73, 219, 657
576 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 32, 36, 48, 64, 72, 96, 144, 192, 288, 576
408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408
117 : 1, 3, 9, 13, 39, 117
418 : 1, 2, 11, 19, 22, 38, 209, 418
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 657,576,408,117,418, is 1.
Now, the common factors can be found like this.
657:3x 3x 73
576:2x 2x 2x 2x 2x 2x 3x 3
408:2x 2x 2x 3x 17
117:3x 3x 13
418:2x 11x 19
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 2x 2x 3x 3x 3x 3x 3 = 3888
Therefore, the value for common factors is 3888.
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 = 7551098919936/(1x3888)
LCM = 7551098919936/3888
LCM = 1942155072
Thus, we can understand that the LCM of 657,576,408,117,418 is 1942155072.
