Find LCM of 357,715,816,224 with Prime Factorization
| 2 | 357, 715, 816, 224 |
| 2 | 357, 715, 408, 112 |
| 2 | 357, 715, 204, 56 |
| 2 | 357, 715, 102, 28 |
| 3 | 357, 715, 51, 14 |
| 7 | 119, 715, 17, 14 |
| 17 | 17, 715, 17, 2 |
| 1, 715, 1, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 7 x 17 x 1 x 715 x 1 x 2 = 8168160
Therefore, the lowest common multiple of 357,715,816,224 is 8168160.
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.
357 x 715 x 816 x 224 = 46656529920
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.
357 : 1, 3, 7, 17, 21, 51, 119, 357
715 : 1, 5, 11, 13, 55, 65, 143, 715
816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816
224 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 112, 224
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 357,715,816,224, is 1.
Now, the common factors can be found like this.
357:3x 7x 17
715:5x 11x 13
816:2x 2x 2x 2x 3x 17
224:2x 2x 2x 2x 2x 7
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 3x 7x 17 = 5712
Therefore, the value for common factors is 5712.
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 = 46656529920/(1x5712)
LCM = 46656529920/5712
LCM = 8168160
Thus, we can understand that the LCM of 357,715,816,224 is 8168160.
