Given numbers are 600,391,905,432,291
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 600,391,905,432,291 is 74139699600.
Find LCM of 600,391,905,432,291 with Prime Factorization
| 2 | 600, 391, 905, 432, 291 |
| 2 | 300, 391, 905, 216, 291 |
| 2 | 150, 391, 905, 108, 291 |
| 3 | 75, 391, 905, 54, 291 |
| 5 | 25, 391, 905, 18, 97 |
| 5, 391, 181, 18, 97 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 5 x 391 x 181 x 18 x 97 = 74139699600
Therefore, the lowest common multiple of 600,391,905,432,291 is 74139699600.
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.
600 x 391 x 905 x 432 x 291 = 26690291856000
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.
600 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 25, 30, 40, 50, 60, 75, 100, 120, 150, 200, 300, 600
391 : 1, 17, 23, 391
905 : 1, 5, 181, 905
432 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 36, 48, 54, 72, 108, 144, 216, 432
291 : 1, 3, 97, 291
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 600,391,905,432,291, is 1.
Now, the common factors can be found like this.
600:2x 2x 2x 3x 5x 5
391:17x 23
905:5x 181
432:2x 2x 2x 2x 3x 3x 3
291:3x 97
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 3x 5 = 360
Therefore, the value for common factors is 360.
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 = 26690291856000/(1x360)
LCM = 26690291856000/360
LCM = 74139699600
Thus, we can understand that the LCM of 600,391,905,432,291 is 74139699600.
