Given numbers are 831,131,775,655
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 831,131,775,655 is 84367275.
Find LCM of 831,131,775,655 with Prime Factorization
5 | 831, 131, 775, 655 |
131 | 831, 131, 155, 131 |
831, 1, 155, 1 |
Multiply the prime numbers at the bottom and the left side.
5 x 131 x 831 x 1 x 155 x 1 = 84367275
Therefore, the lowest common multiple of 831,131,775,655 is 84367275.
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.
831 x 131 x 775 x 655 = 55260565125
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.
831 : 1, 3, 277, 831
131 : 1, 131
775 : 1, 5, 25, 31, 155, 775
655 : 1, 5, 131, 655
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 831,131,775,655, is 1.
Now, the common factors can be found like this.
831:3x 277
131:131
775:5x 5x 31
655:5x 131
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 131 = 655
Therefore, the value for common factors is 655.
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 = 55260565125/(1x655)
LCM = 55260565125/655
LCM = 84367275
Thus, we can understand that the LCM of 831,131,775,655 is 84367275.
