Given numbers are 815,153,905,899,124
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 815,153,905,899,124 is 81160982820.
Find LCM of 815,153,905,899,124 with Prime Factorization
| 5 | 815, 153, 905, 899, 124 |
| 31 | 163, 153, 181, 899, 124 |
| 163, 153, 181, 29, 4 |
Multiply the prime numbers at the bottom and the left side.
5 x 31 x 163 x 153 x 181 x 29 x 4 = 81160982820
Therefore, the lowest common multiple of 815,153,905,899,124 is 81160982820.
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.
815 x 153 x 905 x 899 x 124 = 12579952337100
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.
815 : 1, 5, 163, 815
153 : 1, 3, 9, 17, 51, 153
905 : 1, 5, 181, 905
899 : 1, 29, 31, 899
124 : 1, 2, 4, 31, 62, 124
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 815,153,905,899,124, is 1.
Now, the common factors can be found like this.
815:5x 163
153:3x 3x 17
905:5x 181
899:29x 31
124:2x 2x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 31 = 155
Therefore, the value for common factors is 155.
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 = 12579952337100/(1x155)
LCM = 12579952337100/155
LCM = 81160982820
Thus, we can understand that the LCM of 815,153,905,899,124 is 81160982820.
