Find LCM of 638,812,357,762,552 with Prime Factorization
| 2 | 638, 812, 357, 762, 552 |
| 2 | 319, 406, 357, 381, 276 |
| 3 | 319, 203, 357, 381, 138 |
| 7 | 319, 203, 119, 127, 46 |
| 29 | 319, 29, 17, 127, 46 |
| 11, 1, 17, 127, 46 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 29 x 11 x 1 x 17 x 127 x 46 = 2661217944
Therefore, the lowest common multiple of 638,812,357,762,552 is 2661217944.
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.
638 x 812 x 357 x 762 x 552 = 77792722939008
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.
638 : 1, 2, 11, 22, 29, 58, 319, 638
812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812
357 : 1, 3, 7, 17, 21, 51, 119, 357
762 : 1, 2, 3, 6, 127, 254, 381, 762
552 : 1, 2, 3, 4, 6, 8, 12, 23, 24, 46, 69, 92, 138, 184, 276, 552
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,812,357,762,552, is 1.
Now, the common factors can be found like this.
638:2x 11x 29
812:2x 2x 7x 29
357:3x 7x 17
762:2x 3x 127
552:2x 2x 2x 3x 23
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 7x 29 = 29232
Therefore, the value for common factors is 29232.
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 = 77792722939008/(1x29232)
LCM = 77792722939008/29232
LCM = 2661217944
Thus, we can understand that the LCM of 638,812,357,762,552 is 2661217944.
