Given numbers are 723,930,745,687,350
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 723,930,745,687,350 is 267663890550.
Find LCM of 723,930,745,687,350 with Prime Factorization
| 2 | 723, 930, 745, 687, 350 |
| 3 | 723, 465, 745, 687, 175 |
| 5 | 241, 155, 745, 229, 175 |
| 241, 31, 149, 229, 35 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 241 x 31 x 149 x 229 x 35 = 267663890550
Therefore, the lowest common multiple of 723,930,745,687,350 is 267663890550.
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.
723 x 930 x 745 x 687 x 350 = 120448750747500
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.
723 : 1, 3, 241, 723
930 : 1, 2, 3, 5, 6, 10, 15, 30, 31, 62, 93, 155, 186, 310, 465, 930
745 : 1, 5, 149, 745
687 : 1, 3, 229, 687
350 : 1, 2, 5, 7, 10, 14, 25, 35, 50, 70, 175, 350
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 723,930,745,687,350, is 1.
Now, the common factors can be found like this.
723:3x 241
930:2x 3x 5x 31
745:5x 149
687:3x 229
350:2x 5x 5x 7
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 5 = 450
Therefore, the value for common factors is 450.
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 = 120448750747500/(1x450)
LCM = 120448750747500/450
LCM = 267663890550
Thus, we can understand that the LCM of 723,930,745,687,350 is 267663890550.
