Given numbers are 309,527,403,511,155
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 309,527,403,511,155 is 5408830245.
Find LCM of 309,527,403,511,155 with Prime Factorization
| 31 | 309, 527, 403, 511, 155 |
| 309, 17, 13, 511, 5 |
Multiply the prime numbers at the bottom and the left side.
31 x 309 x 17 x 13 x 511 x 5 = 5408830245
Therefore, the lowest common multiple of 309,527,403,511,155 is 5408830245.
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.
309 x 527 x 403 x 511 x 155 = 5197885865445
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.
309 : 1, 3, 103, 309
527 : 1, 17, 31, 527
403 : 1, 13, 31, 403
511 : 1, 7, 73, 511
155 : 1, 5, 31, 155
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 309,527,403,511,155, is 1.
Now, the common factors can be found like this.
309:3x 103
527:17x 31
403:13x 31
511:7x 73
155:5x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
31x 31 = 961
Therefore, the value for common factors is 961.
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 = 5197885865445/(1x961)
LCM = 5197885865445/961
LCM = 5408830245
Thus, we can understand that the LCM of 309,527,403,511,155 is 5408830245.
