Given numbers are 811,791,460,797,155
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 811,791,460,797,155 is 7290799995220.
Find LCM of 811,791,460,797,155 with Prime Factorization
| 5 | 811, 791, 460, 797, 155 |
| 811, 791, 92, 797, 31 |
Multiply the prime numbers at the bottom and the left side.
5 x 811 x 791 x 92 x 797 x 31 = 7290799995220
Therefore, the lowest common multiple of 811,791,460,797,155 is 7290799995220.
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.
811 x 791 x 460 x 797 x 155 = 36453999976100
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.
811 : 1, 811
791 : 1, 7, 113, 791
460 : 1, 2, 4, 5, 10, 20, 23, 46, 92, 115, 230, 460
797 : 1, 797
155 : 1, 5, 31, 155
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 811,791,460,797,155, is 1.
Now, the common factors can be found like this.
811:811
791:7x 113
460:2x 2x 5x 23
797:797
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.
5 = 5
Therefore, the value for common factors is 5.
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 = 36453999976100/(1x5)
LCM = 36453999976100/5
LCM = 7290799995220
Thus, we can understand that the LCM of 811,791,460,797,155 is 7290799995220.
