Given numbers are 812,901,786,812
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 812,901,786,812 is 287523516.
Find LCM of 812,901,786,812 with Prime Factorization
| 2 | 812, 901, 786, 812 |
| 2 | 406, 901, 393, 406 |
| 7 | 203, 901, 393, 203 |
| 29 | 29, 901, 393, 29 |
| 1, 901, 393, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 29 x 1 x 901 x 393 x 1 = 287523516
Therefore, the lowest common multiple of 812,901,786,812 is 287523516.
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.
812 x 901 x 786 x 812 = 466938189984
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.
812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812
901 : 1, 17, 53, 901
786 : 1, 2, 3, 6, 131, 262, 393, 786
812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 812,901,786,812, is 1.
Now, the common factors can be found like this.
812:2x 2x 7x 29
901:17x 53
786:2x 3x 131
812:2x 2x 7x 29
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 7x 29 = 1624
Therefore, the value for common factors is 1624.
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 = 466938189984/(1x1624)
LCM = 466938189984/1624
LCM = 287523516
Thus, we can understand that the LCM of 812,901,786,812 is 287523516.
