Given numbers are 705,763,170,832,861
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 705,763,170,832,861 is 311939060160.
Find LCM of 705,763,170,832,861 with Prime Factorization
| 2 | 705, 763, 170, 832, 861 |
| 3 | 705, 763, 85, 416, 861 |
| 5 | 235, 763, 85, 416, 287 |
| 7 | 47, 763, 17, 416, 287 |
| 47, 109, 17, 416, 41 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 7 x 47 x 109 x 17 x 416 x 41 = 311939060160
Therefore, the lowest common multiple of 705,763,170,832,861 is 311939060160.
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.
705 x 763 x 170 x 832 x 861 = 65507202633600
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.
705 : 1, 3, 5, 15, 47, 141, 235, 705
763 : 1, 7, 109, 763
170 : 1, 2, 5, 10, 17, 34, 85, 170
832 : 1, 2, 4, 8, 13, 16, 26, 32, 52, 64, 104, 208, 416, 832
861 : 1, 3, 7, 21, 41, 123, 287, 861
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 705,763,170,832,861, is 1.
Now, the common factors can be found like this.
705:3x 5x 47
763:7x 109
170:2x 5x 17
832:2x 2x 2x 2x 2x 2x 13
861:3x 7x 41
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 5x 7 = 210
Therefore, the value for common factors is 210.
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 = 65507202633600/(1x210)
LCM = 65507202633600/210
LCM = 311939060160
Thus, we can understand that the LCM of 705,763,170,832,861 is 311939060160.
