Given numbers are 131,917,294,511
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 131,917,294,511 is 2811522.
Find LCM of 131,917,294,511 with Prime Factorization
| 7 | 131, 917, 294, 511 |
| 131 | 131, 131, 42, 73 |
| 1, 1, 42, 73 |
Multiply the prime numbers at the bottom and the left side.
7 x 131 x 1 x 1 x 42 x 73 = 2811522
Therefore, the lowest common multiple of 131,917,294,511 is 2811522.
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.
131 x 917 x 294 x 511 = 18047159718
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.
131 : 1, 131
917 : 1, 7, 131, 917
294 : 1, 2, 3, 6, 7, 14, 21, 42, 49, 98, 147, 294
511 : 1, 7, 73, 511
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 131,917,294,511, is 1.
Now, the common factors can be found like this.
131:131
917:7x 131
294:2x 3x 7x 7
511:7x 73
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 7x 131 = 6419
Therefore, the value for common factors is 6419.
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 = 18047159718/(1x6419)
LCM = 18047159718/6419
LCM = 2811522
Thus, we can understand that the LCM of 131,917,294,511 is 2811522.
