Given numbers are 315,347,157,990,923
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 315,347,157,990,923 is 348468930810.
Find LCM of 315,347,157,990,923 with Prime Factorization
| 3 | 315, 347, 157, 990, 923 |
| 3 | 105, 347, 157, 330, 923 |
| 5 | 35, 347, 157, 110, 923 |
| 7, 347, 157, 22, 923 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 5 x 7 x 347 x 157 x 22 x 923 = 348468930810
Therefore, the lowest common multiple of 315,347,157,990,923 is 348468930810.
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.
315 x 347 x 157 x 990 x 923 = 15681101886450
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.
315 : 1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, 315
347 : 1, 347
157 : 1, 157
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
923 : 1, 13, 71, 923
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 315,347,157,990,923, is 1.
Now, the common factors can be found like this.
315:3x 3x 5x 7
347:347
157:157
990:2x 3x 3x 5x 11
923:13x 71
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 5 = 45
Therefore, the value for common factors is 45.
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 = 15681101886450/(1x45)
LCM = 15681101886450/45
LCM = 348468930810
Thus, we can understand that the LCM of 315,347,157,990,923 is 348468930810.
