Given numbers are 699,871,738,820,917
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 699,871,738,820,917 is 1373408634780.
Find LCM of 699,871,738,820,917 with Prime Factorization
| 2 | 699, 871, 738, 820, 917 |
| 3 | 699, 871, 369, 410, 917 |
| 41 | 233, 871, 123, 410, 917 |
| 233, 871, 3, 10, 917 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 41 x 233 x 871 x 3 x 10 x 917 = 1373408634780
Therefore, the lowest common multiple of 699,871,738,820,917 is 1373408634780.
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.
699 x 871 x 738 x 820 x 917 = 337858524155880
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.
699 : 1, 3, 233, 699
871 : 1, 13, 67, 871
738 : 1, 2, 3, 6, 9, 18, 41, 82, 123, 246, 369, 738
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
917 : 1, 7, 131, 917
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 699,871,738,820,917, is 1.
Now, the common factors can be found like this.
699:3x 233
871:13x 67
738:2x 3x 3x 41
820:2x 2x 5x 41
917:7x 131
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 41 = 246
Therefore, the value for common factors is 246.
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 = 337858524155880/(1x246)
LCM = 337858524155880/246
LCM = 1373408634780
Thus, we can understand that the LCM of 699,871,738,820,917 is 1373408634780.
