Given numbers are 290,855,393,950
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 290,855,393,950 is 32481450.
Find LCM of 290,855,393,950 with Prime Factorization
| 2 | 290, 855, 393, 950 |
| 3 | 145, 855, 393, 475 |
| 5 | 145, 285, 131, 475 |
| 19 | 29, 57, 131, 95 |
| 29, 3, 131, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 19 x 29 x 3 x 131 x 5 = 32481450
Therefore, the lowest common multiple of 290,855,393,950 is 32481450.
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.
290 x 855 x 393 x 950 = 92572132500
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.
290 : 1, 2, 5, 10, 29, 58, 145, 290
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
393 : 1, 3, 131, 393
950 : 1, 2, 5, 10, 19, 25, 38, 50, 95, 190, 475, 950
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 290,855,393,950, is 1.
Now, the common factors can be found like this.
290:2x 5x 29
855:3x 3x 5x 19
393:3x 131
950:2x 5x 5x 19
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 5x 5x 19 = 2850
Therefore, the value for common factors is 2850.
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 = 92572132500/(1x2850)
LCM = 92572132500/2850
LCM = 32481450
Thus, we can understand that the LCM of 290,855,393,950 is 32481450.
