Find LCM of 694,665,939,168,405 with Prime Factorization
| 2 | 694, 665, 939, 168, 405 |
| 3 | 347, 665, 939, 84, 405 |
| 5 | 347, 665, 313, 28, 135 |
| 7 | 347, 133, 313, 28, 27 |
| 347, 19, 313, 4, 27 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 7 x 347 x 19 x 313 x 4 x 27 = 46802652120
Therefore, the lowest common multiple of 694,665,939,168,405 is 46802652120.
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.
694 x 665 x 939 x 168 x 405 = 29485670835600
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.
694 : 1, 2, 347, 694
665 : 1, 5, 7, 19, 35, 95, 133, 665
939 : 1, 3, 313, 939
168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168
405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 694,665,939,168,405, is 1.
Now, the common factors can be found like this.
694:2x 347
665:5x 7x 19
939:3x 313
168:2x 2x 2x 3x 7
405:3x 3x 3x 3x 5
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 7 = 630
Therefore, the value for common factors is 630.
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 = 29485670835600/(1x630)
LCM = 29485670835600/630
LCM = 46802652120
Thus, we can understand that the LCM of 694,665,939,168,405 is 46802652120.
