Given numbers are 350,203,389,290,431
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 350,203,389,290,431 is 1701738850.
Find LCM of 350,203,389,290,431 with Prime Factorization
| 2 | 350, 203, 389, 290, 431 |
| 5 | 175, 203, 389, 145, 431 |
| 7 | 35, 203, 389, 29, 431 |
| 29 | 5, 29, 389, 29, 431 |
| 5, 1, 389, 1, 431 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 29 x 5 x 1 x 389 x 1 x 431 = 1701738850
Therefore, the lowest common multiple of 350,203,389,290,431 is 1701738850.
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.
350 x 203 x 389 x 290 x 431 = 3454529865500
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.
350 : 1, 2, 5, 7, 10, 14, 25, 35, 50, 70, 175, 350
203 : 1, 7, 29, 203
389 : 1, 389
290 : 1, 2, 5, 10, 29, 58, 145, 290
431 : 1, 431
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 350,203,389,290,431, is 1.
Now, the common factors can be found like this.
350:2x 5x 5x 7
203:7x 29
389:389
290:2x 5x 29
431:431
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 7x 29 = 2030
Therefore, the value for common factors is 2030.
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 = 3454529865500/(1x2030)
LCM = 3454529865500/2030
LCM = 1701738850
Thus, we can understand that the LCM of 350,203,389,290,431 is 1701738850.
