Find LCM of 447,463,309,420,756 with Prime Factorization
| 2 | 447, 463, 309, 420, 756 |
| 2 | 447, 463, 309, 210, 378 |
| 3 | 447, 463, 309, 105, 189 |
| 7 | 149, 463, 103, 35, 63 |
| 149, 463, 103, 5, 9 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 149 x 463 x 103 x 5 x 9 = 26859398580
Therefore, the lowest common multiple of 447,463,309,420,756 is 26859398580.
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.
447 x 463 x 309 x 420 x 756 = 20305705326480
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.
447 : 1, 3, 149, 447
463 : 1, 463
309 : 1, 3, 103, 309
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
756 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 27, 28, 36, 42, 54, 63, 84, 108, 126, 189, 252, 378, 756
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 447,463,309,420,756, is 1.
Now, the common factors can be found like this.
447:3x 149
463:463
309:3x 103
420:2x 2x 3x 5x 7
756:2x 2x 3x 3x 3x 7
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 3x 3x 3x 7 = 756
Therefore, the value for common factors is 756.
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 = 20305705326480/(1x756)
LCM = 20305705326480/756
LCM = 26859398580
Thus, we can understand that the LCM of 447,463,309,420,756 is 26859398580.
