Find LCM of 646,950,448,257,612 with Prime Factorization
| 2 | 646, 950, 448, 257, 612 |
| 2 | 323, 475, 224, 257, 306 |
| 17 | 323, 475, 112, 257, 153 |
| 19 | 19, 475, 112, 257, 9 |
| 1, 25, 112, 257, 9 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 17 x 19 x 1 x 25 x 112 x 257 x 9 = 8367508800
Therefore, the lowest common multiple of 646,950,448,257,612 is 8367508800.
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.
646 x 950 x 448 x 257 x 612 = 43243285478400
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.
646 : 1, 2, 17, 19, 34, 38, 323, 646
950 : 1, 2, 5, 10, 19, 25, 38, 50, 95, 190, 475, 950
448 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 64, 112, 224, 448
257 : 1, 257
612 : 1, 2, 3, 4, 6, 9, 12, 17, 18, 34, 36, 51, 68, 102, 153, 204, 306, 612
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 646,950,448,257,612, is 1.
Now, the common factors can be found like this.
646:2x 17x 19
950:2x 5x 5x 19
448:2x 2x 2x 2x 2x 2x 7
257:257
612:2x 2x 3x 3x 17
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 17x 19 = 5168
Therefore, the value for common factors is 5168.
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 = 43243285478400/(1x5168)
LCM = 43243285478400/5168
LCM = 8367508800
Thus, we can understand that the LCM of 646,950,448,257,612 is 8367508800.
