Given numbers are 180,188,705,856
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 180,188,705,856 is 1810440.
Find LCM of 180,188,705,856 with Prime Factorization
| 2 | 180, 188, 705, 856 |
| 2 | 90, 94, 705, 428 |
| 3 | 45, 47, 705, 214 |
| 5 | 15, 47, 235, 214 |
| 47 | 3, 47, 47, 214 |
| 3, 1, 1, 214 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 47 x 3 x 1 x 1 x 214 = 1810440
Therefore, the lowest common multiple of 180,188,705,856 is 1810440.
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.
180 x 188 x 705 x 856 = 20421763200
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.
180 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90, 180
188 : 1, 2, 4, 47, 94, 188
705 : 1, 3, 5, 15, 47, 141, 235, 705
856 : 1, 2, 4, 8, 107, 214, 428, 856
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 180,188,705,856, is 1.
Now, the common factors can be found like this.
180:2x 2x 3x 3x 5
188:2x 2x 47
705:3x 5x 47
856:2x 2x 2x 107
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 5x 47 = 11280
Therefore, the value for common factors is 11280.
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 = 20421763200/(1x11280)
LCM = 20421763200/11280
LCM = 1810440
Thus, we can understand that the LCM of 180,188,705,856 is 1810440.
