Find LCM of 642,177,568,535,944 with Prime Factorization
| 2 | 642, 177, 568, 535, 944 |
| 2 | 321, 177, 284, 535, 472 |
| 2 | 321, 177, 142, 535, 236 |
| 3 | 321, 177, 71, 535, 118 |
| 59 | 107, 59, 71, 535, 118 |
| 107 | 107, 1, 71, 535, 2 |
| 1, 1, 71, 5, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 59 x 107 x 1 x 1 x 71 x 5 x 2 = 107573520
Therefore, the lowest common multiple of 642,177,568,535,944 is 107573520.
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 177 x 568 x 535 x 944 = 32597358324480
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
177 : 1, 3, 59, 177
568 : 1, 2, 4, 8, 71, 142, 284, 568
535 : 1, 5, 107, 535
944 : 1, 2, 4, 8, 16, 59, 118, 236, 472, 944
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,177,568,535,944, is 1.
Now, the common factors can be found like this.
642:2x 3x 107
177:3x 59
568:2x 2x 2x 71
535:5x 107
944:2x 2x 2x 2x 59
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 59x 107 = 303024
Therefore, the value for common factors is 303024.
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 = 32597358324480/(1x303024)
LCM = 32597358324480/303024
LCM = 107573520
Thus, we can understand that the LCM of 642,177,568,535,944 is 107573520.
