Find LCM of 731,816,912,451,284 with Prime Factorization
2 | 731, 816, 912, 451, 284 |
2 | 731, 408, 456, 451, 142 |
2 | 731, 204, 228, 451, 71 |
2 | 731, 102, 114, 451, 71 |
3 | 731, 51, 57, 451, 71 |
17 | 731, 17, 19, 451, 71 |
43, 1, 19, 451, 71 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 17 x 43 x 1 x 19 x 451 x 71 = 21347504112
Therefore, the lowest common multiple of 731,816,912,451,284 is 21347504112.
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.
731 x 816 x 912 x 451 x 284 = 69678253421568
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.
731 : 1, 17, 43, 731
816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816
912 : 1, 2, 3, 4, 6, 8, 12, 16, 19, 24, 38, 48, 57, 76, 114, 152, 228, 304, 456, 912
451 : 1, 11, 41, 451
284 : 1, 2, 4, 71, 142, 284
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 731,816,912,451,284, is 1.
Now, the common factors can be found like this.
731:17x 43
816:2x 2x 2x 2x 3x 17
912:2x 2x 2x 2x 3x 19
451:11x 41
284:2x 2x 71
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 3x 17 = 3264
Therefore, the value for common factors is 3264.
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 = 69678253421568/(1x3264)
LCM = 69678253421568/3264
LCM = 21347504112
Thus, we can understand that the LCM of 731,816,912,451,284 is 21347504112.
