Given numbers are 609,865,305,393,695
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 609,865,305,393,695 is 585125911965.
Find LCM of 609,865,305,393,695 with Prime Factorization
| 3 | 609, 865, 305, 393, 695 |
| 5 | 203, 865, 305, 131, 695 |
| 203, 173, 61, 131, 139 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 203 x 173 x 61 x 131 x 139 = 585125911965
Therefore, the lowest common multiple of 609,865,305,393,695 is 585125911965.
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.
609 x 865 x 305 x 393 x 695 = 43884443397375
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.
609 : 1, 3, 7, 21, 29, 87, 203, 609
865 : 1, 5, 173, 865
305 : 1, 5, 61, 305
393 : 1, 3, 131, 393
695 : 1, 5, 139, 695
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 609,865,305,393,695, is 1.
Now, the common factors can be found like this.
609:3x 7x 29
865:5x 173
305:5x 61
393:3x 131
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.
3x 5x 5 = 75
Therefore, the value for common factors is 75.
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 = 43884443397375/(1x75)
LCM = 43884443397375/75
LCM = 585125911965
Thus, we can understand that the LCM of 609,865,305,393,695 is 585125911965.
