Given numbers are 298,855,450,788
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 298,855,450,788 is 501936300.
Find LCM of 298,855,450,788 with Prime Factorization
| 2 | 298, 855, 450, 788 |
| 3 | 149, 855, 225, 394 |
| 3 | 149, 285, 75, 394 |
| 5 | 149, 95, 25, 394 |
| 149, 19, 5, 394 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 149 x 19 x 5 x 394 = 501936300
Therefore, the lowest common multiple of 298,855,450,788 is 501936300.
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 855 x 450 x 788 = 90348534000
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
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
450 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 25, 30, 45, 50, 75, 90, 150, 225, 450
788 : 1, 2, 4, 197, 394, 788
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 298,855,450,788, is 1.
Now, the common factors can be found like this.
298:2x 149
855:3x 3x 5x 19
450:2x 3x 3x 5x 5
788:2x 2x 197
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 3x 3x 5 = 180
Therefore, the value for common factors is 180.
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 = 90348534000/(1x180)
LCM = 90348534000/180
LCM = 501936300
Thus, we can understand that the LCM of 298,855,450,788 is 501936300.
