Given numbers are 105,217,677,615,711
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 105,217,677,615,711 is 21412721295.
Find LCM of 105,217,677,615,711 with Prime Factorization
| 3 | 105, 217, 677, 615, 711 |
| 5 | 35, 217, 677, 205, 237 |
| 7 | 7, 217, 677, 41, 237 |
| 1, 31, 677, 41, 237 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 7 x 1 x 31 x 677 x 41 x 237 = 21412721295
Therefore, the lowest common multiple of 105,217,677,615,711 is 21412721295.
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.
105 x 217 x 677 x 615 x 711 = 6745007207925
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.
105 : 1, 3, 5, 7, 15, 21, 35, 105
217 : 1, 7, 31, 217
677 : 1, 677
615 : 1, 3, 5, 15, 41, 123, 205, 615
711 : 1, 3, 9, 79, 237, 711
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 105,217,677,615,711, is 1.
Now, the common factors can be found like this.
105:3x 5x 7
217:7x 31
677:677
615:3x 5x 41
711:3x 3x 79
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 5x 7 = 315
Therefore, the value for common factors is 315.
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 = 6745007207925/(1x315)
LCM = 6745007207925/315
LCM = 21412721295
Thus, we can understand that the LCM of 105,217,677,615,711 is 21412721295.
