Find LCM of 464,378,252,621,820 with Prime Factorization
| 2 | 464, 378, 252, 621, 820 |
| 2 | 232, 189, 126, 621, 410 |
| 3 | 116, 189, 63, 621, 205 |
| 3 | 116, 21, 63, 207, 205 |
| 3 | 116, 7, 21, 69, 205 |
| 7 | 116, 7, 7, 23, 205 |
| 116, 1, 1, 23, 205 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 3 x 7 x 116 x 1 x 1 x 23 x 205 = 413486640
Therefore, the lowest common multiple of 464,378,252,621,820 is 413486640.
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.
464 x 378 x 252 x 621 x 820 = 22506904788480
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.
464 : 1, 2, 4, 8, 16, 29, 58, 116, 232, 464
378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378
252 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 28, 36, 42, 63, 84, 126, 252
621 : 1, 3, 9, 23, 27, 69, 207, 621
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 464,378,252,621,820, is 1.
Now, the common factors can be found like this.
464:2x 2x 2x 2x 29
378:2x 3x 3x 3x 7
252:2x 2x 3x 3x 7
621:3x 3x 3x 23
820:2x 2x 5x 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 2x 2x 2x 2x 3x 3x 3x 3x 3x 7 = 54432
Therefore, the value for common factors is 54432.
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 = 22506904788480/(1x54432)
LCM = 22506904788480/54432
LCM = 413486640
Thus, we can understand that the LCM of 464,378,252,621,820 is 413486640.
