Given numbers are 109,668,581,686,648
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 109,668,581,686,648 is 335807342136.
Find LCM of 109,668,581,686,648 with Prime Factorization
| 2 | 109, 668, 581, 686, 648 |
| 2 | 109, 334, 581, 343, 324 |
| 7 | 109, 167, 581, 343, 162 |
| 109, 167, 83, 49, 162 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 109 x 167 x 83 x 49 x 162 = 335807342136
Therefore, the lowest common multiple of 109,668,581,686,648 is 335807342136.
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.
109 x 668 x 581 x 686 x 648 = 18805211159616
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.
109 : 1, 109
668 : 1, 2, 4, 167, 334, 668
581 : 1, 7, 83, 581
686 : 1, 2, 7, 14, 49, 98, 343, 686
648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 109,668,581,686,648, is 1.
Now, the common factors can be found like this.
109:109
668:2x 2x 167
581:7x 83
686:2x 7x 7x 7
648:2x 2x 2x 3x 3x 3x 3
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 7 = 56
Therefore, the value for common factors is 56.
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 = 18805211159616/(1x56)
LCM = 18805211159616/56
LCM = 335807342136
Thus, we can understand that the LCM of 109,668,581,686,648 is 335807342136.
