Given numbers are 543,251,615,697
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 543,251,615,697 is 474981105.
Find LCM of 543,251,615,697 with Prime Factorization
| 3 | 543, 251, 615, 697 |
| 41 | 181, 251, 205, 697 |
| 181, 251, 5, 17 |
Multiply the prime numbers at the bottom and the left side.
3 x 41 x 181 x 251 x 5 x 17 = 474981105
Therefore, the lowest common multiple of 543,251,615,697 is 474981105.
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 251 x 615 x 697 = 58422675915
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
251 : 1, 251
615 : 1, 3, 5, 15, 41, 123, 205, 615
697 : 1, 17, 41, 697
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 543,251,615,697, is 1.
Now, the common factors can be found like this.
543:3x 181
251:251
615:3x 5x 41
697:17x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 41 = 123
Therefore, the value for common factors is 123.
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 = 58422675915/(1x123)
LCM = 58422675915/123
LCM = 474981105
Thus, we can understand that the LCM of 543,251,615,697 is 474981105.
