Given numbers are 177,781,781,285,607
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 177,781,781,285,607 is 7971436605.
Find LCM of 177,781,781,285,607 with Prime Factorization
| 3 | 177, 781, 781, 285, 607 |
| 11 | 59, 781, 781, 95, 607 |
| 71 | 59, 71, 71, 95, 607 |
| 59, 1, 1, 95, 607 |
Multiply the prime numbers at the bottom and the left side.
3 x 11 x 71 x 59 x 1 x 1 x 95 x 607 = 7971436605
Therefore, the lowest common multiple of 177,781,781,285,607 is 7971436605.
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.
177 x 781 x 781 x 285 x 607 = 18677075965515
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.
177 : 1, 3, 59, 177
781 : 1, 11, 71, 781
781 : 1, 11, 71, 781
285 : 1, 3, 5, 15, 19, 57, 95, 285
607 : 1, 607
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 177,781,781,285,607, is 1.
Now, the common factors can be found like this.
177:3x 59
781:11x 71
781:11x 71
285:3x 5x 19
607:607
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 11x 71 = 2343
Therefore, the value for common factors is 2343.
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 = 18677075965515/(1x2343)
LCM = 18677075965515/2343
LCM = 7971436605
Thus, we can understand that the LCM of 177,781,781,285,607 is 7971436605.
