Given numbers are 613,561,786,960
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 613,561,786,960 is 14415994560.
Find LCM of 613,561,786,960 with Prime Factorization
| 2 | 613, 561, 786, 960 |
| 3 | 613, 561, 393, 480 |
| 613, 187, 131, 160 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 613 x 187 x 131 x 160 = 14415994560
Therefore, the lowest common multiple of 613,561,786,960 is 14415994560.
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.
613 x 561 x 786 x 960 = 259487902080
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.
613 : 1, 613
561 : 1, 3, 11, 17, 33, 51, 187, 561
786 : 1, 2, 3, 6, 131, 262, 393, 786
960 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 64, 80, 96, 120, 160, 192, 240, 320, 480, 960
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 613,561,786,960, is 1.
Now, the common factors can be found like this.
613:613
561:3x 11x 17
786:2x 3x 131
960:2x 2x 2x 2x 2x 2x 3x 5
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 3 = 18
Therefore, the value for common factors is 18.
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 = 259487902080/(1x18)
LCM = 259487902080/18
LCM = 14415994560
Thus, we can understand that the LCM of 613,561,786,960 is 14415994560.
