Given numbers are 321,174,940,496,746
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 321,174,940,496,746 is 404726275920.
Find LCM of 321,174,940,496,746 with Prime Factorization
| 2 | 321, 174, 940, 496, 746 |
| 2 | 321, 87, 470, 248, 373 |
| 3 | 321, 87, 235, 124, 373 |
| 107, 29, 235, 124, 373 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 107 x 29 x 235 x 124 x 373 = 404726275920
Therefore, the lowest common multiple of 321,174,940,496,746 is 404726275920.
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.
321 x 174 x 940 x 496 x 746 = 19426861244160
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.
321 : 1, 3, 107, 321
174 : 1, 2, 3, 6, 29, 58, 87, 174
940 : 1, 2, 4, 5, 10, 20, 47, 94, 188, 235, 470, 940
496 : 1, 2, 4, 8, 16, 31, 62, 124, 248, 496
746 : 1, 2, 373, 746
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 321,174,940,496,746, is 1.
Now, the common factors can be found like this.
321:3x 107
174:2x 3x 29
940:2x 2x 5x 47
496:2x 2x 2x 2x 31
746:2x 373
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 2x 3 = 48
Therefore, the value for common factors is 48.
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 = 19426861244160/(1x48)
LCM = 19426861244160/48
LCM = 404726275920
Thus, we can understand that the LCM of 321,174,940,496,746 is 404726275920.
