Find LCM of 456,497,820,280,330 with Prime Factorization
| 2 | 456, 497, 820, 280, 330 |
| 2 | 228, 497, 410, 140, 165 |
| 2 | 114, 497, 205, 70, 165 |
| 3 | 57, 497, 205, 35, 165 |
| 5 | 19, 497, 205, 35, 55 |
| 7 | 19, 497, 41, 7, 11 |
| 19, 71, 41, 1, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 7 x 19 x 71 x 41 x 1 x 11 = 511055160
Therefore, the lowest common multiple of 456,497,820,280,330 is 511055160.
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.
456 x 497 x 820 x 280 x 330 = 17171453376000
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.
456 : 1, 2, 3, 4, 6, 8, 12, 19, 24, 38, 57, 76, 114, 152, 228, 456
497 : 1, 7, 71, 497
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280
330 : 1, 2, 3, 5, 6, 10, 11, 15, 22, 30, 33, 55, 66, 110, 165, 330
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 456,497,820,280,330, is 1.
Now, the common factors can be found like this.
456:2x 2x 2x 3x 19
497:7x 71
820:2x 2x 5x 41
280:2x 2x 2x 5x 7
330:2x 3x 5x 11
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 2x 2x 3x 5x 5x 7 = 33600
Therefore, the value for common factors is 33600.
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 = 17171453376000/(1x33600)
LCM = 17171453376000/33600
LCM = 511055160
Thus, we can understand that the LCM of 456,497,820,280,330 is 511055160.
