Given numbers are 786,418,781,181
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 786,418,781,181 is 2111085174.
Find LCM of 786,418,781,181 with Prime Factorization
| 2 | 786, 418, 781, 181 |
| 11 | 393, 209, 781, 181 |
| 393, 19, 71, 181 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 393 x 19 x 71 x 181 = 2111085174
Therefore, the lowest common multiple of 786,418,781,181 is 2111085174.
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.
786 x 418 x 781 x 181 = 46443873828
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.
786 : 1, 2, 3, 6, 131, 262, 393, 786
418 : 1, 2, 11, 19, 22, 38, 209, 418
781 : 1, 11, 71, 781
181 : 1, 181
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 786,418,781,181, is 1.
Now, the common factors can be found like this.
786:2x 3x 131
418:2x 11x 19
781:11x 71
181:181
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 11 = 22
Therefore, the value for common factors is 22.
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 = 46443873828/(1x22)
LCM = 46443873828/22
LCM = 2111085174
Thus, we can understand that the LCM of 786,418,781,181 is 2111085174.
