Given numbers are 154,861,474,786,822
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 154,861,474,786,822 is 26856213846.
Find LCM of 154,861,474,786,822 with Prime Factorization
| 2 | 154, 861, 474, 786, 822 |
| 3 | 77, 861, 237, 393, 411 |
| 7 | 77, 287, 79, 131, 137 |
| 11, 41, 79, 131, 137 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 11 x 41 x 79 x 131 x 137 = 26856213846
Therefore, the lowest common multiple of 154,861,474,786,822 is 26856213846.
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.
154 x 861 x 474 x 786 x 822 = 40606595335152
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.
154 : 1, 2, 7, 11, 14, 22, 77, 154
861 : 1, 3, 7, 21, 41, 123, 287, 861
474 : 1, 2, 3, 6, 79, 158, 237, 474
786 : 1, 2, 3, 6, 131, 262, 393, 786
822 : 1, 2, 3, 6, 137, 274, 411, 822
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 154,861,474,786,822, is 1.
Now, the common factors can be found like this.
154:2x 7x 11
861:3x 7x 41
474:2x 3x 79
786:2x 3x 131
822:2x 3x 137
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 3x 3x 3x 7 = 1512
Therefore, the value for common factors is 1512.
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 = 40606595335152/(1x1512)
LCM = 40606595335152/1512
LCM = 26856213846
Thus, we can understand that the LCM of 154,861,474,786,822 is 26856213846.
