Find LCM of 642,576,517,540,297 with Prime Factorization
| 2 | 642, 576, 517, 540, 297 |
| 2 | 321, 288, 517, 270, 297 |
| 3 | 321, 144, 517, 135, 297 |
| 3 | 107, 48, 517, 45, 99 |
| 3 | 107, 16, 517, 15, 33 |
| 11 | 107, 16, 517, 5, 11 |
| 107, 16, 47, 5, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 3 x 11 x 107 x 16 x 47 x 5 x 1 = 477956160
Therefore, the lowest common multiple of 642,576,517,540,297 is 477956160.
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.
642 x 576 x 517 x 540 x 297 = 30661843576320
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.
642 : 1, 2, 3, 6, 107, 214, 321, 642
576 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 32, 36, 48, 64, 72, 96, 144, 192, 288, 576
517 : 1, 11, 47, 517
540 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 27, 30, 36, 45, 54, 60, 90, 108, 135, 180, 270, 540
297 : 1, 3, 9, 11, 27, 33, 99, 297
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,576,517,540,297, is 1.
Now, the common factors can be found like this.
642:2x 3x 107
576:2x 2x 2x 2x 2x 2x 3x 3
517:11x 47
540:2x 2x 3x 3x 3x 5
297:3x 3x 3x 11
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 3x 3x 3x 3x 3x 3x 11 = 64152
Therefore, the value for common factors is 64152.
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 = 30661843576320/(1x64152)
LCM = 30661843576320/64152
LCM = 477956160
Thus, we can understand that the LCM of 642,576,517,540,297 is 477956160.
