Find LCM of 854,122,328,705,990 with Prime Factorization
| 2 | 854, 122, 328, 705, 990 |
| 3 | 427, 61, 164, 705, 495 |
| 5 | 427, 61, 164, 235, 165 |
| 61 | 427, 61, 164, 47, 33 |
| 7, 1, 164, 47, 33 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 61 x 7 x 1 x 164 x 47 x 33 = 3258402840
Therefore, the lowest common multiple of 854,122,328,705,990 is 3258402840.
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.
854 x 122 x 328 x 705 x 990 = 23851508788800
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.
854 : 1, 2, 7, 14, 61, 122, 427, 854
122 : 1, 2, 61, 122
328 : 1, 2, 4, 8, 41, 82, 164, 328
705 : 1, 3, 5, 15, 47, 141, 235, 705
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 854,122,328,705,990, is 1.
Now, the common factors can be found like this.
854:2x 7x 61
122:2x 61
328:2x 2x 2x 41
705:3x 5x 47
990:2x 3x 3x 5x 11
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 3x 5x 61 = 7320
Therefore, the value for common factors is 7320.
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 = 23851508788800/(1x7320)
LCM = 23851508788800/7320
LCM = 3258402840
Thus, we can understand that the LCM of 854,122,328,705,990 is 3258402840.
