Given numbers are 707,289,486,556,731
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 707,289,486,556,731 is 1187043891012.
Find LCM of 707,289,486,556,731 with Prime Factorization
| 2 | 707, 289, 486, 556, 731 |
| 17 | 707, 289, 243, 278, 731 |
| 707, 17, 243, 278, 43 |
Multiply the prime numbers at the bottom and the left side.
2 x 17 x 707 x 17 x 243 x 278 x 43 = 1187043891012
Therefore, the lowest common multiple of 707,289,486,556,731 is 1187043891012.
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.
707 x 289 x 486 x 556 x 731 = 40359492294408
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.
707 : 1, 7, 101, 707
289 : 1, 17, 289
486 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162, 243, 486
556 : 1, 2, 4, 139, 278, 556
731 : 1, 17, 43, 731
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 707,289,486,556,731, is 1.
Now, the common factors can be found like this.
707:7x 101
289:17x 17
486:2x 3x 3x 3x 3x 3
556:2x 2x 139
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 17 = 34
Therefore, the value for common factors is 34.
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 = 40359492294408/(1x34)
LCM = 40359492294408/34
LCM = 1187043891012
Thus, we can understand that the LCM of 707,289,486,556,731 is 1187043891012.
