Given numbers are 188,564,638,960
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 188,564,638,960 is 14393280.
Find LCM of 188,564,638,960 with Prime Factorization
| 2 | 188, 564, 638, 960 |
| 2 | 94, 282, 319, 480 |
| 3 | 47, 141, 319, 240 |
| 47 | 47, 47, 319, 80 |
| 1, 1, 319, 80 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 47 x 1 x 1 x 319 x 80 = 14393280
Therefore, the lowest common multiple of 188,564,638,960 is 14393280.
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.
188 x 564 x 638 x 960 = 64942479360
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.
188 : 1, 2, 4, 47, 94, 188
564 : 1, 2, 3, 4, 6, 12, 47, 94, 141, 188, 282, 564
638 : 1, 2, 11, 22, 29, 58, 319, 638
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
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 188,564,638,960, is 2.
Now, the common factors can be found like this.
188:2x 2x 47
564:2x 2x 3x 47
638:2x 11x 29
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 2x 2x 2x 3x 47 = 2256
Therefore, the value for common factors is 2256.
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 = 64942479360/(2x2256)
LCM = 64942479360/4512
LCM = 14393280
Thus, we can understand that the LCM of 188,564,638,960 is 14393280.
