Given numbers are 891,471,570,670,178
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 891,471,570,670,178 is 158487774390.
Find LCM of 891,471,570,670,178 with Prime Factorization
| 2 | 891, 471, 570, 670, 178 |
| 3 | 891, 471, 285, 335, 89 |
| 5 | 297, 157, 95, 335, 89 |
| 297, 157, 19, 67, 89 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 297 x 157 x 19 x 67 x 89 = 158487774390
Therefore, the lowest common multiple of 891,471,570,670,178 is 158487774390.
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.
891 x 471 x 570 x 670 x 178 = 28527799390200
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.
891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
471 : 1, 3, 157, 471
570 : 1, 2, 3, 5, 6, 10, 15, 19, 30, 38, 57, 95, 114, 190, 285, 570
670 : 1, 2, 5, 10, 67, 134, 335, 670
178 : 1, 2, 89, 178
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 891,471,570,670,178, is 1.
Now, the common factors can be found like this.
891:3x 3x 3x 3x 11
471:3x 157
570:2x 3x 5x 19
670:2x 5x 67
178:2x 89
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 = 28527799390200/(1x180)
LCM = 28527799390200/180
LCM = 158487774390
Thus, we can understand that the LCM of 891,471,570,670,178 is 158487774390.
