Given numbers are 813,345,580,765,670
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 813,345,580,765,670 is 37058800140.
Find LCM of 813,345,580,765,670 with Prime Factorization
| 2 | 813, 345, 580, 765, 670 |
| 3 | 813, 345, 290, 765, 335 |
| 5 | 271, 115, 290, 255, 335 |
| 271, 23, 58, 51, 67 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 271 x 23 x 58 x 51 x 67 = 37058800140
Therefore, the lowest common multiple of 813,345,580,765,670 is 37058800140.
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.
813 x 345 x 580 x 765 x 670 = 83382300315000
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.
813 : 1, 3, 271, 813
345 : 1, 3, 5, 15, 23, 69, 115, 345
580 : 1, 2, 4, 5, 10, 20, 29, 58, 116, 145, 290, 580
765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765
670 : 1, 2, 5, 10, 67, 134, 335, 670
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 813,345,580,765,670, is 1.
Now, the common factors can be found like this.
813:3x 271
345:3x 5x 23
580:2x 2x 5x 29
765:3x 3x 5x 17
670:2x 5x 67
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 3x 5x 5x 5 = 2250
Therefore, the value for common factors is 2250.
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 = 83382300315000/(1x2250)
LCM = 83382300315000/2250
LCM = 37058800140
Thus, we can understand that the LCM of 813,345,580,765,670 is 37058800140.
