Given numbers are 543,765,918,647
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 543,765,918,647 is 537521130.
Find LCM of 543,765,918,647 with Prime Factorization
| 3 | 543, 765, 918, 647 |
| 3 | 181, 255, 306, 647 |
| 17 | 181, 85, 102, 647 |
| 181, 5, 6, 647 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 17 x 181 x 5 x 6 x 647 = 537521130
Therefore, the lowest common multiple of 543,765,918,647 is 537521130.
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 765 x 918 x 647 = 246722198670
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
765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765
918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918
647 : 1, 647
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 543,765,918,647, is 1.
Now, the common factors can be found like this.
543:3x 181
765:3x 3x 5x 17
918:2x 3x 3x 3x 17
647:647
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 17 = 459
Therefore, the value for common factors is 459.
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 = 246722198670/(1x459)
LCM = 246722198670/459
LCM = 537521130
Thus, we can understand that the LCM of 543,765,918,647 is 537521130.
