Find LCM of 612,731,872,537,656 with Prime Factorization
| 2 | 612, 731, 872, 537, 656 |
| 2 | 306, 731, 436, 537, 328 |
| 2 | 153, 731, 218, 537, 164 |
| 3 | 153, 731, 109, 537, 82 |
| 17 | 51, 731, 109, 179, 82 |
| 3, 43, 109, 179, 82 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 17 x 3 x 43 x 109 x 179 x 82 = 84206042064
Therefore, the lowest common multiple of 612,731,872,537,656 is 84206042064.
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.
612 x 731 x 872 x 537 x 656 = 137424260648448
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.
612 : 1, 2, 3, 4, 6, 9, 12, 17, 18, 34, 36, 51, 68, 102, 153, 204, 306, 612
731 : 1, 17, 43, 731
872 : 1, 2, 4, 8, 109, 218, 436, 872
537 : 1, 3, 179, 537
656 : 1, 2, 4, 8, 16, 41, 82, 164, 328, 656
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 612,731,872,537,656, is 1.
Now, the common factors can be found like this.
612:2x 2x 3x 3x 17
731:17x 43
872:2x 2x 2x 109
537:3x 179
656:2x 2x 2x 2x 41
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 3x 17 = 1632
Therefore, the value for common factors is 1632.
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 = 137424260648448/(1x1632)
LCM = 137424260648448/1632
LCM = 84206042064
Thus, we can understand that the LCM of 612,731,872,537,656 is 84206042064.
