Find LCM of 480,384,661,402,912 with Prime Factorization
| 2 | 480, 384, 661, 402, 912 |
| 2 | 240, 192, 661, 201, 456 |
| 2 | 120, 96, 661, 201, 228 |
| 2 | 60, 48, 661, 201, 114 |
| 2 | 30, 24, 661, 201, 57 |
| 3 | 15, 12, 661, 201, 57 |
| 5, 4, 661, 67, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 2 x 3 x 5 x 4 x 661 x 67 x 19 = 1615589760
Therefore, the lowest common multiple of 480,384,661,402,912 is 1615589760.
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.
480 x 384 x 661 x 402 x 912 = 44667825684480
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.
480 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 80, 96, 120, 160, 240, 480
384 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 384
661 : 1, 661
402 : 1, 2, 3, 6, 67, 134, 201, 402
912 : 1, 2, 3, 4, 6, 8, 12, 16, 19, 24, 38, 48, 57, 76, 114, 152, 228, 304, 456, 912
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 480,384,661,402,912, is 1.
Now, the common factors can be found like this.
480:2x 2x 2x 2x 2x 3x 5
384:2x 2x 2x 2x 2x 2x 2x 3
661:661
402:2x 3x 67
912:2x 2x 2x 2x 3x 19
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 2x 2x 2x 2x 3x 3x 3 = 27648
Therefore, the value for common factors is 27648.
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 = 44667825684480/(1x27648)
LCM = 44667825684480/27648
LCM = 1615589760
Thus, we can understand that the LCM of 480,384,661,402,912 is 1615589760.
