Given numbers are 872,494,603,756
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 872,494,603,756 is 2727407592.
Find LCM of 872,494,603,756 with Prime Factorization
| 2 | 872, 494, 603, 756 |
| 2 | 436, 247, 603, 378 |
| 3 | 218, 247, 603, 189 |
| 3 | 218, 247, 201, 63 |
| 218, 247, 67, 21 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 218 x 247 x 67 x 21 = 2727407592
Therefore, the lowest common multiple of 872,494,603,756 is 2727407592.
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.
872 x 494 x 603 x 756 = 196373346624
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.
872 : 1, 2, 4, 8, 109, 218, 436, 872
494 : 1, 2, 13, 19, 26, 38, 247, 494
603 : 1, 3, 9, 67, 201, 603
756 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 27, 28, 36, 42, 54, 63, 84, 108, 126, 189, 252, 378, 756
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 872,494,603,756, is 1.
Now, the common factors can be found like this.
872:2x 2x 2x 109
494:2x 13x 19
603:3x 3x 67
756:2x 2x 3x 3x 3x 7
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 3 = 72
Therefore, the value for common factors is 72.
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 = 196373346624/(1x72)
LCM = 196373346624/72
LCM = 2727407592
Thus, we can understand that the LCM of 872,494,603,756 is 2727407592.
