Find LCM of 642,563,663,494,153 with Prime Factorization
| 2 | 642, 563, 663, 494, 153 |
| 3 | 321, 563, 663, 247, 153 |
| 13 | 107, 563, 221, 247, 51 |
| 17 | 107, 563, 17, 19, 51 |
| 107, 563, 1, 19, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 17 x 107 x 563 x 1 x 19 x 3 = 4553135262
Therefore, the lowest common multiple of 642,563,663,494,153 is 4553135262.
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 563 x 663 x 494 x 153 = 18112372072236
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
563 : 1, 563
663 : 1, 3, 13, 17, 39, 51, 221, 663
494 : 1, 2, 13, 19, 26, 38, 247, 494
153 : 1, 3, 9, 17, 51, 153
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,563,663,494,153, is 1.
Now, the common factors can be found like this.
642:2x 3x 107
563:563
663:3x 13x 17
494:2x 13x 19
153:3x 3x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 13x 17 = 3978
Therefore, the value for common factors is 3978.
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 = 18112372072236/(1x3978)
LCM = 18112372072236/3978
LCM = 4553135262
Thus, we can understand that the LCM of 642,563,663,494,153 is 4553135262.
