Given numbers are 549,143,273,419
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 549,143,273,419 is 230261031.
Find LCM of 549,143,273,419 with Prime Factorization
| 3 | 549, 143, 273, 419 |
| 13 | 183, 143, 91, 419 |
| 183, 11, 7, 419 |
Multiply the prime numbers at the bottom and the left side.
3 x 13 x 183 x 11 x 7 x 419 = 230261031
Therefore, the lowest common multiple of 549,143,273,419 is 230261031.
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.
549 x 143 x 273 x 419 = 8980180209
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.
549 : 1, 3, 9, 61, 183, 549
143 : 1, 11, 13, 143
273 : 1, 3, 7, 13, 21, 39, 91, 273
419 : 1, 419
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 549,143,273,419, is 1.
Now, the common factors can be found like this.
549:3x 3x 61
143:11x 13
273:3x 7x 13
419:419
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 13 = 39
Therefore, the value for common factors is 39.
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 = 8980180209/(1x39)
LCM = 8980180209/39
LCM = 230261031
Thus, we can understand that the LCM of 549,143,273,419 is 230261031.
