Find LCM of 621,605,865,346,246 with Prime Factorization
| 2 | 621, 605, 865, 346, 246 |
| 3 | 621, 605, 865, 173, 123 |
| 5 | 207, 605, 865, 173, 41 |
| 173 | 207, 121, 173, 173, 41 |
| 207, 121, 1, 1, 41 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 173 x 207 x 121 x 1 x 1 x 41 = 5329751130
Therefore, the lowest common multiple of 621,605,865,346,246 is 5329751130.
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.
621 x 605 x 865 x 346 x 246 = 27661408364700
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.
621 : 1, 3, 9, 23, 27, 69, 207, 621
605 : 1, 5, 11, 55, 121, 605
865 : 1, 5, 173, 865
346 : 1, 2, 173, 346
246 : 1, 2, 3, 6, 41, 82, 123, 246
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 621,605,865,346,246, is 1.
Now, the common factors can be found like this.
621:3x 3x 3x 23
605:5x 11x 11
865:5x 173
346:2x 173
246:2x 3x 41
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 5x 173 = 5190
Therefore, the value for common factors is 5190.
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 = 27661408364700/(1x5190)
LCM = 27661408364700/5190
LCM = 5329751130
Thus, we can understand that the LCM of 621,605,865,346,246 is 5329751130.
