Given numbers are 785,382,849,772,255
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 785,382,849,772,255 is 1670617152060.
Find LCM of 785,382,849,772,255 with Prime Factorization
| 2 | 785, 382, 849, 772, 255 |
| 3 | 785, 191, 849, 386, 255 |
| 5 | 785, 191, 283, 386, 85 |
| 157, 191, 283, 386, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 157 x 191 x 283 x 386 x 17 = 1670617152060
Therefore, the lowest common multiple of 785,382,849,772,255 is 1670617152060.
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.
785 x 382 x 849 x 772 x 255 = 50118514561800
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.
785 : 1, 5, 157, 785
382 : 1, 2, 191, 382
849 : 1, 3, 283, 849
772 : 1, 2, 4, 193, 386, 772
255 : 1, 3, 5, 15, 17, 51, 85, 255
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 785,382,849,772,255, is 1.
Now, the common factors can be found like this.
785:5x 157
382:2x 191
849:3x 283
772:2x 2x 193
255:3x 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 3x 5 = 30
Therefore, the value for common factors is 30.
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 = 50118514561800/(1x30)
LCM = 50118514561800/30
LCM = 1670617152060
Thus, we can understand that the LCM of 785,382,849,772,255 is 1670617152060.
