Find LCM of 390,654,630,477,446 with Prime Factorization
| 2 | 390, 654, 630, 477, 446 |
| 3 | 195, 327, 315, 477, 223 |
| 3 | 65, 109, 105, 159, 223 |
| 5 | 65, 109, 35, 53, 223 |
| 13, 109, 7, 53, 223 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 13 x 109 x 7 x 53 x 223 = 10550939490
Therefore, the lowest common multiple of 390,654,630,477,446 is 10550939490.
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.
390 x 654 x 630 x 477 x 446 = 34185043947600
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.
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
654 : 1, 2, 3, 6, 109, 218, 327, 654
630 : 1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, 630
477 : 1, 3, 9, 53, 159, 477
446 : 1, 2, 223, 446
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 390,654,630,477,446, is 1.
Now, the common factors can be found like this.
390:2x 3x 5x 13
654:2x 3x 109
630:2x 3x 3x 5x 7
477:3x 3x 53
446:2x 223
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 3x 3x 3x 5 = 3240
Therefore, the value for common factors is 3240.
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 = 34185043947600/(1x3240)
LCM = 34185043947600/3240
LCM = 10550939490
Thus, we can understand that the LCM of 390,654,630,477,446 is 10550939490.
