Given numbers are 298,696,447,555
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 298,696,447,555 is 19185240.
Find LCM of 298,696,447,555 with Prime Factorization
| 2 | 298, 696, 447, 555 |
| 3 | 149, 348, 447, 555 |
| 149 | 149, 116, 149, 185 |
| 1, 116, 1, 185 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 149 x 1 x 116 x 1 x 185 = 19185240
Therefore, the lowest common multiple of 298,696,447,555 is 19185240.
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.
298 x 696 x 447 x 555 = 51454813680
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.
298 : 1, 2, 149, 298
696 : 1, 2, 3, 4, 6, 8, 12, 24, 29, 58, 87, 116, 174, 232, 348, 696
447 : 1, 3, 149, 447
555 : 1, 3, 5, 15, 37, 111, 185, 555
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 298,696,447,555, is 1.
Now, the common factors can be found like this.
298:2x 149
696:2x 2x 2x 3x 29
447:3x 149
555:3x 5x 37
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 149 = 2682
Therefore, the value for common factors is 2682.
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 = 51454813680/(1x2682)
LCM = 51454813680/2682
LCM = 19185240
Thus, we can understand that the LCM of 298,696,447,555 is 19185240.
