Given numbers are 418,304,455,533
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 418,304,455,533 is 62382320.
Find LCM of 418,304,455,533 with Prime Factorization
| 2 | 418, 304, 455, 533 |
| 13 | 209, 152, 455, 533 |
| 19 | 209, 152, 35, 41 |
| 11, 8, 35, 41 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 19 x 11 x 8 x 35 x 41 = 62382320
Therefore, the lowest common multiple of 418,304,455,533 is 62382320.
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.
418 x 304 x 455 x 533 = 30816866080
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.
418 : 1, 2, 11, 19, 22, 38, 209, 418
304 : 1, 2, 4, 8, 16, 19, 38, 76, 152, 304
455 : 1, 5, 7, 13, 35, 65, 91, 455
533 : 1, 13, 41, 533
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 418,304,455,533, is 1.
Now, the common factors can be found like this.
418:2x 11x 19
304:2x 2x 2x 2x 19
455:5x 7x 13
533:13x 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 13x 19 = 494
Therefore, the value for common factors is 494.
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 = 30816866080/(1x494)
LCM = 30816866080/494
LCM = 62382320
Thus, we can understand that the LCM of 418,304,455,533 is 62382320.
