Given numbers are 891,391,786,472,177
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 891,391,786,472,177 is 21541093992.
Find LCM of 891,391,786,472,177 with Prime Factorization
| 2 | 891, 391, 786, 472, 177 |
| 3 | 891, 391, 393, 236, 177 |
| 59 | 297, 391, 131, 236, 59 |
| 297, 391, 131, 4, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 59 x 297 x 391 x 131 x 4 x 1 = 21541093992
Therefore, the lowest common multiple of 891,391,786,472,177 is 21541093992.
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 391 x 786 x 472 x 177 = 22876641819504
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
391 : 1, 17, 23, 391
786 : 1, 2, 3, 6, 131, 262, 393, 786
472 : 1, 2, 4, 8, 59, 118, 236, 472
177 : 1, 3, 59, 177
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 891,391,786,472,177, is 1.
Now, the common factors can be found like this.
891:3x 3x 3x 3x 11
391:17x 23
786:2x 3x 131
472:2x 2x 2x 59
177:3x 59
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 59 = 1062
Therefore, the value for common factors is 1062.
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 = 22876641819504/(1x1062)
LCM = 22876641819504/1062
LCM = 21541093992
Thus, we can understand that the LCM of 891,391,786,472,177 is 21541093992.
