Given numbers are 165,788,870,894
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 165,788,870,894 is 561816420.
Find LCM of 165,788,870,894 with Prime Factorization
| 2 | 165, 788, 870, 894 |
| 3 | 165, 394, 435, 447 |
| 5 | 55, 394, 145, 149 |
| 11, 394, 29, 149 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 11 x 394 x 29 x 149 = 561816420
Therefore, the lowest common multiple of 165,788,870,894 is 561816420.
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.
165 x 788 x 870 x 894 = 101126955600
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.
165 : 1, 3, 5, 11, 15, 33, 55, 165
788 : 1, 2, 4, 197, 394, 788
870 : 1, 2, 3, 5, 6, 10, 15, 29, 30, 58, 87, 145, 174, 290, 435, 870
894 : 1, 2, 3, 6, 149, 298, 447, 894
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 165,788,870,894, is 1.
Now, the common factors can be found like this.
165:3x 5x 11
788:2x 2x 197
870:2x 3x 5x 29
894:2x 3x 149
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 5 = 180
Therefore, the value for common factors is 180.
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 = 101126955600/(1x180)
LCM = 101126955600/180
LCM = 561816420
Thus, we can understand that the LCM of 165,788,870,894 is 561816420.
