Given numbers are 155,754,815,815
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 155,754,815,815 is 19049810.
Find LCM of 155,754,815,815 with Prime Factorization
5 | 155, 754, 815, 815 |
163 | 31, 754, 163, 163 |
31, 754, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
5 x 163 x 31 x 754 x 1 x 1 = 19049810
Therefore, the lowest common multiple of 155,754,815,815 is 19049810.
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.
155 x 754 x 815 x 815 = 77627975750
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.
155 : 1, 5, 31, 155
754 : 1, 2, 13, 26, 29, 58, 377, 754
815 : 1, 5, 163, 815
815 : 1, 5, 163, 815
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 155,754,815,815, is 1.
Now, the common factors can be found like this.
155:5x 31
754:2x 13x 29
815:5x 163
815:5x 163
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 5x 163 = 4075
Therefore, the value for common factors is 4075.
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 = 77627975750/(1x4075)
LCM = 77627975750/4075
LCM = 19049810
Thus, we can understand that the LCM of 155,754,815,815 is 19049810.
