Given numbers are 809,209,145,695
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 809,209,145,695 is 3407827555.
Find LCM of 809,209,145,695 with Prime Factorization
| 5 | 809, 209, 145, 695 |
| 809, 209, 29, 139 |
Multiply the prime numbers at the bottom and the left side.
5 x 809 x 209 x 29 x 139 = 3407827555
Therefore, the lowest common multiple of 809,209,145,695 is 3407827555.
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.
809 x 209 x 145 x 695 = 17039137775
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.
809 : 1, 809
209 : 1, 11, 19, 209
145 : 1, 5, 29, 145
695 : 1, 5, 139, 695
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 809,209,145,695, is 1.
Now, the common factors can be found like this.
809:809
209:11x 19
145:5x 29
695:5x 139
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5 = 5
Therefore, the value for common factors is 5.
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 = 17039137775/(1x5)
LCM = 17039137775/5
LCM = 3407827555
Thus, we can understand that the LCM of 809,209,145,695 is 3407827555.
