Given numbers are 120,326,964,736,689
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 120,326,964,736,689 is 298808496480.
Find LCM of 120,326,964,736,689 with Prime Factorization
| 2 | 120, 326, 964, 736, 689 |
| 2 | 60, 163, 482, 368, 689 |
| 2 | 30, 163, 241, 184, 689 |
| 15, 163, 241, 92, 689 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 15 x 163 x 241 x 92 x 689 = 298808496480
Therefore, the lowest common multiple of 120,326,964,736,689 is 298808496480.
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.
120 x 326 x 964 x 736 x 689 = 19123743774720
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.
120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120
326 : 1, 2, 163, 326
964 : 1, 2, 4, 241, 482, 964
736 : 1, 2, 4, 8, 16, 23, 32, 46, 92, 184, 368, 736
689 : 1, 13, 53, 689
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 120,326,964,736,689, is 1.
Now, the common factors can be found like this.
120:2x 2x 2x 3x 5
326:2x 163
964:2x 2x 241
736:2x 2x 2x 2x 2x 23
689:13x 53
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 2x 2x 2 = 64
Therefore, the value for common factors is 64.
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 = 19123743774720/(1x64)
LCM = 19123743774720/64
LCM = 298808496480
Thus, we can understand that the LCM of 120,326,964,736,689 is 298808496480.
