Given numbers are 647,917,507,131
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 647,917,507,131 is 300802593.
Find LCM of 647,917,507,131 with Prime Factorization
| 131 | 647, 917, 507, 131 |
| 647, 7, 507, 1 |
Multiply the prime numbers at the bottom and the left side.
131 x 647 x 7 x 507 x 1 = 300802593
Therefore, the lowest common multiple of 647,917,507,131 is 300802593.
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.
647 x 917 x 507 x 131 = 39405139683
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.
647 : 1, 647
917 : 1, 7, 131, 917
507 : 1, 3, 13, 39, 169, 507
131 : 1, 131
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 647,917,507,131, is 1.
Now, the common factors can be found like this.
647:647
917:7x 131
507:3x 13x 13
131:131
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
131 = 131
Therefore, the value for common factors is 131.
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 = 39405139683/(1x131)
LCM = 39405139683/131
LCM = 300802593
Thus, we can understand that the LCM of 647,917,507,131 is 300802593.
