Find LCM of 957,480,382,242,640 with Prime Factorization
| 2 | 957, 480, 382, 242, 640 |
| 2 | 957, 240, 191, 121, 320 |
| 2 | 957, 120, 191, 121, 160 |
| 2 | 957, 60, 191, 121, 80 |
| 2 | 957, 30, 191, 121, 40 |
| 3 | 957, 15, 191, 121, 20 |
| 5 | 319, 5, 191, 121, 20 |
| 11 | 319, 1, 191, 121, 4 |
| 29, 1, 191, 11, 4 |
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 11 x 29 x 1 x 191 x 11 x 4 = 1286820480
Therefore, the lowest common multiple of 957,480,382,242,640 is 1286820480.
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.
957 x 480 x 382 x 242 x 640 = 27177648537600
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.
957 : 1, 3, 11, 29, 33, 87, 319, 957
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
382 : 1, 2, 191, 382
242 : 1, 2, 11, 22, 121, 242
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 957,480,382,242,640, is 1.
Now, the common factors can be found like this.
957:3x 11x 29
480:2x 2x 2x 2x 2x 3x 5
382:2x 191
242:2x 11x 11
640:2x 2x 2x 2x 2x 2x 2x 5
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 3x 5x 11 = 21120
Therefore, the value for common factors is 21120.
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 = 27177648537600/(1x21120)
LCM = 27177648537600/21120
LCM = 1286820480
Thus, we can understand that the LCM of 957,480,382,242,640 is 1286820480.
