Given numbers are 548,618,998,822,478
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 548,618,998,822,478 is 20194703652.
Find LCM of 548,618,998,822,478 with Prime Factorization
| 2 | 548, 618, 998, 822, 478 |
| 3 | 274, 309, 499, 411, 239 |
| 137 | 274, 103, 499, 137, 239 |
| 2, 103, 499, 1, 239 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 137 x 2 x 103 x 499 x 1 x 239 = 20194703652
Therefore, the lowest common multiple of 548,618,998,822,478 is 20194703652.
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.
548 x 618 x 998 x 822 x 478 = 132800371215552
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.
548 : 1, 2, 4, 137, 274, 548
618 : 1, 2, 3, 6, 103, 206, 309, 618
998 : 1, 2, 499, 998
822 : 1, 2, 3, 6, 137, 274, 411, 822
478 : 1, 2, 239, 478
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 548,618,998,822,478, is 2.
Now, the common factors can be found like this.
548:2x 2x 137
618:2x 3x 103
998:2x 499
822:2x 3x 137
478:2x 239
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 3x 137 = 3288
Therefore, the value for common factors is 3288.
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 = 132800371215552/(2x3288)
LCM = 132800371215552/6576
LCM = 20194703652
Thus, we can understand that the LCM of 548,618,998,822,478 is 20194703652.
