Find LCM of 855,934,146,180,399 with Prime Factorization
| 2 | 855, 934, 146, 180, 399 |
| 3 | 855, 467, 73, 90, 399 |
| 3 | 285, 467, 73, 30, 133 |
| 5 | 95, 467, 73, 10, 133 |
| 19 | 19, 467, 73, 2, 133 |
| 1, 467, 73, 2, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 19 x 1 x 467 x 73 x 2 x 7 = 816138540
Therefore, the lowest common multiple of 855,934,146,180,399 is 816138540.
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.
855 x 934 x 146 x 180 x 399 = 8373581420400
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.
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
934 : 1, 2, 467, 934
146 : 1, 2, 73, 146
180 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90, 180
399 : 1, 3, 7, 19, 21, 57, 133, 399
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 855,934,146,180,399, is 1.
Now, the common factors can be found like this.
855:3x 3x 5x 19
934:2x 467
146:2x 73
180:2x 2x 3x 3x 5
399:3x 7x 19
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 3x 3x 5x 19 = 10260
Therefore, the value for common factors is 10260.
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 = 8373581420400/(1x10260)
LCM = 8373581420400/10260
LCM = 816138540
Thus, we can understand that the LCM of 855,934,146,180,399 is 816138540.
