Find LCM of 427,280,510,646,352 with Prime Factorization
| 2 | 427, 280, 510, 646, 352 |
| 2 | 427, 140, 255, 323, 176 |
| 2 | 427, 70, 255, 323, 88 |
| 5 | 427, 35, 255, 323, 44 |
| 7 | 427, 7, 51, 323, 44 |
| 17 | 61, 1, 51, 323, 44 |
| 61, 1, 3, 19, 44 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 7 x 17 x 61 x 1 x 3 x 19 x 44 = 728222880
Therefore, the lowest common multiple of 427,280,510,646,352 is 728222880.
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.
427 x 280 x 510 x 646 x 352 = 13865363635200
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.
427 : 1, 7, 61, 427
280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280
510 : 1, 2, 3, 5, 6, 10, 15, 17, 30, 34, 51, 85, 102, 170, 255, 510
646 : 1, 2, 17, 19, 34, 38, 323, 646
352 : 1, 2, 4, 8, 11, 16, 22, 32, 44, 88, 176, 352
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 427,280,510,646,352, is 1.
Now, the common factors can be found like this.
427:7x 61
280:2x 2x 2x 5x 7
510:2x 3x 5x 17
646:2x 17x 19
352:2x 2x 2x 2x 2x 11
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 5x 7x 17 = 19040
Therefore, the value for common factors is 19040.
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 = 13865363635200/(1x19040)
LCM = 13865363635200/19040
LCM = 728222880
Thus, we can understand that the LCM of 427,280,510,646,352 is 728222880.
