Given numbers are 543,647,654,912,861
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 543,647,654,912,861 is 3341073952272.
Find LCM of 543,647,654,912,861 with Prime Factorization
| 2 | 543, 647, 654, 912, 861 |
| 3 | 543, 647, 327, 456, 861 |
| 181, 647, 109, 152, 287 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 181 x 647 x 109 x 152 x 287 = 3341073952272
Therefore, the lowest common multiple of 543,647,654,912,861 is 3341073952272.
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.
543 x 647 x 654 x 912 x 861 = 180417993422688
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.
543 : 1, 3, 181, 543
647 : 1, 647
654 : 1, 2, 3, 6, 109, 218, 327, 654
912 : 1, 2, 3, 4, 6, 8, 12, 16, 19, 24, 38, 48, 57, 76, 114, 152, 228, 304, 456, 912
861 : 1, 3, 7, 21, 41, 123, 287, 861
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 543,647,654,912,861, is 1.
Now, the common factors can be found like this.
543:3x 181
647:647
654:2x 3x 109
912:2x 2x 2x 2x 3x 19
861:3x 7x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 3 = 54
Therefore, the value for common factors is 54.
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 = 180417993422688/(1x54)
LCM = 180417993422688/54
LCM = 3341073952272
Thus, we can understand that the LCM of 543,647,654,912,861 is 3341073952272.
