Find LCM of 420,759,460,382 with Prime Factorization
| 2 | 420, 759, 460, 382 |
| 2 | 210, 759, 230, 191 |
| 3 | 105, 759, 115, 191 |
| 5 | 35, 253, 115, 191 |
| 23 | 7, 253, 23, 191 |
| 7, 11, 1, 191 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 23 x 7 x 11 x 1 x 191 = 20295660
Therefore, the lowest common multiple of 420,759,460,382 is 20295660.
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.
420 x 759 x 460 x 382 = 56016021600
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.
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
759 : 1, 3, 11, 23, 33, 69, 253, 759
460 : 1, 2, 4, 5, 10, 20, 23, 46, 92, 115, 230, 460
382 : 1, 2, 191, 382
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 420,759,460,382, is 1.
Now, the common factors can be found like this.
420:2x 2x 3x 5x 7
759:3x 11x 23
460:2x 2x 5x 23
382:2x 191
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 3x 5x 23 = 2760
Therefore, the value for common factors is 2760.
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 = 56016021600/(1x2760)
LCM = 56016021600/2760
LCM = 20295660
Thus, we can understand that the LCM of 420,759,460,382 is 20295660.
