Find LCM of 207,820,455,788,453 with Prime Factorization
| 2 | 207, 820, 455, 788, 453 |
| 2 | 207, 410, 455, 394, 453 |
| 3 | 207, 205, 455, 197, 453 |
| 5 | 69, 205, 455, 197, 151 |
| 69, 41, 91, 197, 151 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 69 x 41 x 91 x 197 x 151 = 459482275980
Therefore, the lowest common multiple of 207,820,455,788,453 is 459482275980.
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.
207 x 820 x 455 x 788 x 453 = 27568936558800
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.
207 : 1, 3, 9, 23, 69, 207
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
455 : 1, 5, 7, 13, 35, 65, 91, 455
788 : 1, 2, 4, 197, 394, 788
453 : 1, 3, 151, 453
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 207,820,455,788,453, is 1.
Now, the common factors can be found like this.
207:3x 3x 23
820:2x 2x 5x 41
455:5x 7x 13
788:2x 2x 197
453:3x 151
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 5 = 60
Therefore, the value for common factors is 60.
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 = 27568936558800/(1x60)
LCM = 27568936558800/60
LCM = 459482275980
Thus, we can understand that the LCM of 207,820,455,788,453 is 459482275980.
