Given numbers are 186,445,840,242,863
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 186,445,840,242,863 is 242006567880.
Find LCM of 186,445,840,242,863 with Prime Factorization
| 2 | 186, 445, 840, 242, 863 |
| 3 | 93, 445, 420, 121, 863 |
| 5 | 31, 445, 140, 121, 863 |
| 31, 89, 28, 121, 863 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 31 x 89 x 28 x 121 x 863 = 242006567880
Therefore, the lowest common multiple of 186,445,840,242,863 is 242006567880.
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.
186 x 445 x 840 x 242 x 863 = 14520394072800
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.
186 : 1, 2, 3, 6, 31, 62, 93, 186
445 : 1, 5, 89, 445
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
242 : 1, 2, 11, 22, 121, 242
863 : 1, 863
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 186,445,840,242,863, is 1.
Now, the common factors can be found like this.
186:2x 3x 31
445:5x 89
840:2x 2x 2x 3x 5x 7
242:2x 11x 11
863:863
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 3x 5 = 60
Therefore, the value for common factors is 60.
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 = 14520394072800/(1x60)
LCM = 14520394072800/60
LCM = 242006567880
Thus, we can understand that the LCM of 186,445,840,242,863 is 242006567880.
