Given numbers are 642,854,198,573,816
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 642,854,198,573,816 is 234989857872.
Find LCM of 642,854,198,573,816 with Prime Factorization
| 2 | 642, 854, 198, 573, 816 |
| 3 | 321, 427, 99, 573, 408 |
| 107, 427, 33, 191, 136 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 107 x 427 x 33 x 191 x 136 = 234989857872
Therefore, the lowest common multiple of 642,854,198,573,816 is 234989857872.
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 854 x 198 x 573 x 816 = 50757809300352
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
854 : 1, 2, 7, 14, 61, 122, 427, 854
198 : 1, 2, 3, 6, 9, 11, 18, 22, 33, 66, 99, 198
573 : 1, 3, 191, 573
816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,854,198,573,816, is 1.
Now, the common factors can be found like this.
642:2x 3x 107
854:2x 7x 61
198:2x 3x 3x 11
573:3x 191
816:2x 2x 2x 2x 3x 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 2x 2x 3x 3x 3 = 216
Therefore, the value for common factors is 216.
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 = 50757809300352/(1x216)
LCM = 50757809300352/216
LCM = 234989857872
Thus, we can understand that the LCM of 642,854,198,573,816 is 234989857872.
