Find LCM of 642,535,671,814,510 with Prime Factorization
| 2 | 642, 535, 671, 814, 510 |
| 3 | 321, 535, 671, 407, 255 |
| 5 | 107, 535, 671, 407, 85 |
| 11 | 107, 107, 671, 407, 17 |
| 107 | 107, 107, 61, 37, 17 |
| 1, 1, 61, 37, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 11 x 107 x 1 x 1 x 61 x 37 x 17 = 1354809390
Therefore, the lowest common multiple of 642,535,671,814,510 is 1354809390.
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 535 x 671 x 814 x 510 = 95676639121800
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
535 : 1, 5, 107, 535
671 : 1, 11, 61, 671
814 : 1, 2, 11, 22, 37, 74, 407, 814
510 : 1, 2, 3, 5, 6, 10, 15, 17, 30, 34, 51, 85, 102, 170, 255, 510
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,535,671,814,510, is 1.
Now, the common factors can be found like this.
642:2x 3x 107
535:5x 107
671:11x 61
814:2x 11x 37
510:2x 3x 5x 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 2x 3x 5x 11x 107 = 70620
Therefore, the value for common factors is 70620.
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 = 95676639121800/(1x70620)
LCM = 95676639121800/70620
LCM = 1354809390
Thus, we can understand that the LCM of 642,535,671,814,510 is 1354809390.
