Find LCM of 343,731,368,672,930 with Prime Factorization
| 2 | 343, 731, 368, 672, 930 |
| 2 | 343, 731, 184, 336, 465 |
| 2 | 343, 731, 92, 168, 465 |
| 2 | 343, 731, 46, 84, 465 |
| 3 | 343, 731, 23, 42, 465 |
| 7 | 343, 731, 23, 14, 155 |
| 49, 731, 23, 2, 155 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 7 x 49 x 731 x 23 x 2 x 155 = 85810861920
Therefore, the lowest common multiple of 343,731,368,672,930 is 85810861920.
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.
343 x 731 x 368 x 672 x 930 = 57664899210240
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.
343 : 1, 7, 49, 343
731 : 1, 17, 43, 731
368 : 1, 2, 4, 8, 16, 23, 46, 92, 184, 368
672 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 32, 42, 48, 56, 84, 96, 112, 168, 224, 336, 672
930 : 1, 2, 3, 5, 6, 10, 15, 30, 31, 62, 93, 155, 186, 310, 465, 930
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 343,731,368,672,930, is 1.
Now, the common factors can be found like this.
343:7x 7x 7
731:17x 43
368:2x 2x 2x 2x 23
672:2x 2x 2x 2x 2x 3x 7
930:2x 3x 5x 31
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 7 = 672
Therefore, the value for common factors is 672.
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 = 57664899210240/(1x672)
LCM = 57664899210240/672
LCM = 85810861920
Thus, we can understand that the LCM of 343,731,368,672,930 is 85810861920.
