Find LCM of 262,705,688,561,731 with Prime Factorization
| 2 | 262, 705, 688, 561, 731 |
| 3 | 131, 705, 344, 561, 731 |
| 17 | 131, 235, 344, 187, 731 |
| 43 | 131, 235, 344, 11, 43 |
| 131, 235, 8, 11, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 17 x 43 x 131 x 235 x 8 x 11 x 1 = 11882024880
Therefore, the lowest common multiple of 262,705,688,561,731 is 11882024880.
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.
262 x 705 x 688 x 561 x 731 = 52114561123680
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.
262 : 1, 2, 131, 262
705 : 1, 3, 5, 15, 47, 141, 235, 705
688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688
561 : 1, 3, 11, 17, 33, 51, 187, 561
731 : 1, 17, 43, 731
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 262,705,688,561,731, is 1.
Now, the common factors can be found like this.
262:2x 131
705:3x 5x 47
688:2x 2x 2x 2x 43
561:3x 11x 17
731:17x 43
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 17x 43 = 4386
Therefore, the value for common factors is 4386.
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 = 52114561123680/(1x4386)
LCM = 52114561123680/4386
LCM = 11882024880
Thus, we can understand that the LCM of 262,705,688,561,731 is 11882024880.
