Given numbers are 849,623,217,155
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 849,623,217,155 is 81983685.
Find LCM of 849,623,217,155 with Prime Factorization
7 | 849, 623, 217, 155 |
31 | 849, 89, 31, 155 |
849, 89, 1, 5 |
Multiply the prime numbers at the bottom and the left side.
7 x 31 x 849 x 89 x 1 x 5 = 81983685
Therefore, the lowest common multiple of 849,623,217,155 is 81983685.
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.
849 x 623 x 217 x 155 = 17790459645
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.
849 : 1, 3, 283, 849
623 : 1, 7, 89, 623
217 : 1, 7, 31, 217
155 : 1, 5, 31, 155
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 849,623,217,155, is 1.
Now, the common factors can be found like this.
849:3x 283
623:7x 89
217:7x 31
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.
7x 31 = 217
Therefore, the value for common factors is 217.
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 = 17790459645/(1x217)
LCM = 17790459645/217
LCM = 81983685
Thus, we can understand that the LCM of 849,623,217,155 is 81983685.
