Find LCM of 286,735,646,273 with Prime Factorization
| 2 | 286, 735, 646, 273 |
| 3 | 143, 735, 323, 273 |
| 7 | 143, 245, 323, 91 |
| 13 | 143, 35, 323, 13 |
| 11, 35, 323, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 13 x 11 x 35 x 323 x 1 = 67897830
Therefore, the lowest common multiple of 286,735,646,273 is 67897830.
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.
286 x 735 x 646 x 273 = 37072215180
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.
286 : 1, 2, 11, 13, 22, 26, 143, 286
735 : 1, 3, 5, 7, 15, 21, 35, 49, 105, 147, 245, 735
646 : 1, 2, 17, 19, 34, 38, 323, 646
273 : 1, 3, 7, 13, 21, 39, 91, 273
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 286,735,646,273, is 1.
Now, the common factors can be found like this.
286:2x 11x 13
735:3x 5x 7x 7
646:2x 17x 19
273:3x 7x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 7x 13 = 546
Therefore, the value for common factors is 546.
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 = 37072215180/(1x546)
LCM = 37072215180/546
LCM = 67897830
Thus, we can understand that the LCM of 286,735,646,273 is 67897830.
