Find LCM of 474,476,646,912 with Prime Factorization
| 2 | 474, 476, 646, 912 |
| 2 | 237, 238, 323, 456 |
| 3 | 237, 119, 323, 228 |
| 17 | 79, 119, 323, 76 |
| 19 | 79, 7, 19, 76 |
| 79, 7, 1, 4 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 17 x 19 x 79 x 7 x 1 x 4 = 8573712
Therefore, the lowest common multiple of 474,476,646,912 is 8573712.
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.
474 x 476 x 646 x 912 = 132926830848
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.
474 : 1, 2, 3, 6, 79, 158, 237, 474
476 : 1, 2, 4, 7, 14, 17, 28, 34, 68, 119, 238, 476
646 : 1, 2, 17, 19, 34, 38, 323, 646
912 : 1, 2, 3, 4, 6, 8, 12, 16, 19, 24, 38, 48, 57, 76, 114, 152, 228, 304, 456, 912
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 474,476,646,912, is 2.
Now, the common factors can be found like this.
474:2x 3x 79
476:2x 2x 7x 17
646:2x 17x 19
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 3x 17x 19 = 7752
Therefore, the value for common factors is 7752.
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 = 132926830848/(2x7752)
LCM = 132926830848/15504
LCM = 8573712
Thus, we can understand that the LCM of 474,476,646,912 is 8573712.
